The ultimate starship designer,
powered by a deep game simulation...

Cosmoteer is a starship design, simulation, and battle game. Design a fleet of ships by laying out individual rooms and corridors, including cannons, lasers, shields, and thrusters. Battle other starships to earn bounties and use that money to expand your own ship. A dynamic crew and combat simulation makes every design decision important and interesting.

Best-In-Class Starship Designer

Design the greatest starship ever made using a starship designer that is easy-to-learn yet limitlessly flexible.

Build your ship by placing individual modules onto a grid—weapons, defenses, engines, reactors, crew's quarters, and more! Few restrictions and no pre-defined, creativity-limiting hull shapes mean you can create almost any ship you can imagine.

Learn the game systems by watching as your crew scramble to power and operate new modules in real-time as you add them. The Ship Designer is directly integrated into the gameplay—no need to interrupt your flow to tweak your ship or experiment with a new design.

Inspired by professional art programs, the Ship Designer has a variety of different brush sizes and shape tools, as well as full support for Undo & Redo, Copy & Paste, rotation, and mirroring, so you can quickly and easily design giant starships. It even has a "blueprint mode" which allows you to plan for the future and design without restriction.

Intelligent Crew Simulation

Every starship is operated by a crew numbering from half-a-dozen to hundreds—sometimes more than a thousand—of individually-simulated people.

A ship's crew is its lifeblood. Crew not only operate its controls, but they also carry supplies such as ammunition and power batteries to weapons and systems. When a weapon wants to shoot, the crew go pick up ammo or batteries at an ammo factory or reactor and bring them to the weapon—all simulated in real-time down to the individual people and supplies.

Crew are pretty smart and act mostly on their own, which is a good thing since there can be so many. Your crew are smart enough to figure out what controls need operating, what systems need ammo or power, and how best to get around your ship. They're even smart enough to avoid routes that are already jammed with other people.

The crew simulation is what makes starship design so interesting, because how fast a cannon can shoot or how long a shield can stay charged depends directly on how quickly crew can deliver ammo or power to it. As a player, you'll have to think carefully about how you design your ship's layout so that it operates at peak efficiency without exposing its more vulnerable (and sometimes explosive!) systems.

Physics That Matter

Every ship is part of a realistic 2D physics simulation. Ships have weight and a center-of-mass depending on their size and shape. Small ships with lots of thrusters are realistically fast and nimble, while large ships with proportionally fewer thrusters are naturally slower and more difficult to maneuver.

The position and orientation of your ship's thrusters affects its movement. Thrusters near its center-of-mass are great at pushing the ship forward, whereas off-center thrusters are effective at rotating the ship. Thrusters pointing forward are needed to decelerate, while thrusters pointing to the sides will let it strafe.

The A.I. will control your ship's thrusters, automatically determining the optimal ignition level for each thruster in order to fly your ship wherever you tell it to go.

Ships can collide and block weapons fire. The shape of a ship determines its collision properties. Weapons must be placed in locations that have good line-of-sight to the enemy, otherwise the ship will block its own shots.

Emergent Combat Model

Weapons obey the laws of the physics simulation. Whether or not a cannon or laser hits an enemy depends not on a roll of the dice but upon the physics of the weapon and its target.

Damage is modeled module-by-module, and each module can be individually targeted & destroyed. There's no big "health bar" for the whole ship—a ship is only "dead" once all of the modules that it needs to function are gone.

Some modules can explode causing collateral damage to the surrounding modules. This means that you'll have to think carefully about where you place your reactors and munitions. Too close to the edge and they'll be exposed to enemy fire; too far and your weapons won't fire fast enough.

Ships can break apart into multiple pieces when their connecting modules are destroyed. Usually this will be a crippling blow, but any piece that has a control room, power, and thrusters can continue to operate independently, potentially remaining a threat to the enemy.

Epic Tactical Strategy

Classic RTS-style controls make the game easy to learn. Simply right-click where you want your ship to fly, or right-click on an enemy to attack it. Advanced controls let you adjust the orientation, distance, and angle of attack.

Target your weapons to focus their fire on the vulnerable parts of enemy ships. Do you take out the weapons first, go for the explosive power core, or eliminate the command-and-control center? Every ship is different, and the right strategy varies greatly.

Command a fleet of ships, outmaneuvering and flanking the enemy to expose its weak side. Specialize your fleet's ships into roles however you see fit.

Starship Painter

The surface of a ship is like an artist's canvas. The Ship Painter is even easier to use than the Ship Designer, requiring no drawing ability to make your ship look great.

Pick a color and texture to customize your ship's basic appearance. If you're not artistically inclined then no need to do more, but otherwise you can...

Add decals to decorate your ship. Every ship has two independently-colored layers of decals. Decals are small shapes, icons, symbols, letters, and numbers that you can stamp on your ship to give it extra visual flourish.

Painting your ship is free and has no effect on gameplay.

Bounty Hunter

You are a bounty hunter, traveling from sector to sector, hunting down renegade enemies and destroying them.

Earn money for every enemy vanquished. Use your income to repair and upgrade your own ship, growing bigger and more powerful with every victory.

Explore a galaxy in search of bigger and more powerful enemies. As your own ship grows in size and power, you will soon be able to defeat even the strongest foes.

Expand your fleet by purchasing additional ships. The galaxy will crumble before your almighty armada!

Creative Mode

Play in a creative sandbox mode if being a bounty hunter isn't your cup of Earl Grey.

Design ships with unlimited funds. The only limit in Creative Mode is your imagination! (And the power of your computer.)

Pit your designs against each other and import designs from other players, competing to be the master designer.

Or just turn on the A.I., sit back, and watch massive fleets annihilate each other! (Great for hosting A.I.-controlled tournaments!)


Battle your friends and enemies in real-time, pitting your designs against theirs. Compete to be the master "Starship Architect & Commander" against up to 7 other players in Team vs Team and Free For All battles.

Configure a variety of game options by specifying number of ships, total funds, game speed, and other options. Play tiny skirmishes, massive fleet battles, or anywhere in between.

Play online in public or private lobbies. Local Area Network and direct I.P. address connections are also supported.

Important Note: Multiplayer is NOT SUPPORTED between 32-bit and 64-bit operating systems!

And more!

Everything you should expect from a great PC game, including customizable controls, windowed and borderless display modes, support for high-resolution displays, no mandatory locked framerates, and dozens of other options to tailor the game to your own preferences.

Attention to accessibility issues wherever possible in order to support gamers of all abilities. Every single control and mouse button can be remapped, the user interface can be made twice as big, and colors that convey meaningful information can be freely changed.

Unobtrusive tutorials that don't interrupt gameplay and are easy to dismiss or turn off altogether. There's no special "tutorial level" you need to play through—the context-sensitive tips are built-in to the main Bounty Hunter mode.

A mods manager makes it easy to install and uninstall mods created by the Cosmoteer community. A powerful modding framework lets mods change literally any part of the game data, opening up a universe of possibilities beyond the base game.

Cosmoteer update 0.14.2 is now available! In addition to a ton of bug fixes and minor improvements, this update has three major features: Heavy Laser Blasters, Boost Thrusters, and an advanced user interface for controlling your ship.

Heavy Laser Blaster

The "Heavy Laser Blaster" is a larger, double-barreled variant of the regular Laser Blaster.

In its primary firing mode, the Heavy Laser Blaster shoots two laser shots at once, each doing more than twice the damage of a single shot from the regular Laser Blaster. It can also be changed to an "alternating" firing mode which fires twice as fast but only one shot at a time.

If you need an increase in raw firepower, the Heavy Laser Blaster can be a worthy upgrade over the regular Laser Blaster, albeit at the expense of some versatility with its reduced firing rate, arc, and shot speed.

Boost Thruster

The "Boost Thruster" is a longer variant of the Large Thruster. Ordinarily, it provides exactly the same thruster force as the Large Thruster, but it also has a special "boost mode" that, when activated, triples its thrust force at the expense of greatly-increased power consumption.

When activated, not only does its power consumption increase proportionally with its thrust, but it also continuously drains power regardless of whether it's actually thrusting, making the Boost Thruster much less power efficient per unit-of-thrust than when not in boost mode. And when boost mode is turned off, any remaining power is immediately lost, meaning you need to think tactically about when to use it.

The Boost Thruster's boost mode is most useful for when you need to quickly get away from—or get closer to—the enemy, or to make a quick maneuver. Be careful though, because once boost mode runs out of power or is turned off, you'll have to wait for your crew to bring more power to the boost thruster before it's usable again even in non-boosted mode.

Advanced Ship Controls

This update also adds a handful of advanced ship controls that can be useful for performing special maneuvers or taking certain actions that can't be done by just right-clicking.

In the top-left of the grid of six buttons is the move command. Just click the button (or press its hotkey, which happens to be M) and then click in empty space to move your ship there or click on another ship to follow it. This isn't much different than just right-clicking in empty space or on a friendly ship to follow it, but it does allow you to "follow" enemy or junk ships without having to attack them.

Below it in the bottom-left of the grid is the force-move command. This is just like the regular move command but disables all collision avoidance, meaning you can use it to ram enemy ships. (And unlike the move command, clicking on an enemy ship won't follow it; it'll just tell your ship to move onto its location.)

In the middle of the top row is the attack command. As its name implies, this command can be used to attack enemy ships, but it can also be used to attack your own or other friendly ships if you really want to. (Doing so will turn on friendly-fire damage for the specific ship you're attacking.) And if you're already attacking a ship, this command doubles as a convenient way to quickly adjust the current distance and angle of attack—just click the command (or press T) and click in empty space to set a location relative to the enemy.

In the middle of the bottom row is the rotate command. This command can be used to quickly change your ship's rotation without altering its movement destination or attack distance/angle. Just press it or its hotkey (R) and then click where you want your ship to face.

In the bottom-right is the strafe command. This is a variant of the move command that can be used when you want to move your ship to a location while keeping its current rotation. It's especially useful when you want to make a tactical maneuver while still facing the enemy.

And in the top-right is the oft-requested halt command. Clicking this or using its hotkey will immediately cancel all current commands, causing your ship to slow to a halt.

Lastly, when you select a specific weapon (or weapons), there is now a target command (seen below in the top-right of the grid). This command is primarily useful for if you want a weapon to target a specific part on a friendly ship, or even its own ship.

By default, these advanced controls are actually hidden until "Show Advanced Ship Controls" in the gameplay settings is turned on. (This setting is also turned on automatically when the "Advanced Ship Controls" tutorial is viewed for the first time.)

I`m very pleased to see this kind of game.
Good tactics for slow moving ships is in large number of fast bomber pods, and counter-measure systems, so rocket tactic become useless.
Only means to defeat this beasts is rapid heavy laser fire on close range.
Thanks for free download, and best luck
