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 an interface that is easy-to-learn yet incredibly flexible.

Build your ship by placing individual modules onto a grid—weapons, shields, 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.

The exterior of a ship is like an artist's canvas, but it requires no drawing ability to make your ship look great! Simply pick a color and texture to customize your ship's basic appearance, then optionally add decals such as shapes, symbols, and letters to give it extra visual flourish. Painting your ship is free and has no effect on gameplay.

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.

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!) modules.

Physics-Driven Flight & Combat

Every ship is part of a 2D physics simulation, and the position and orientation of its thrusters realistically affects its movement. Small ships with lots of thrusters are fast and nimble, while large ships with proportionally fewer thrusters are naturally slower and more difficult to maneuver.

Weapons obey the laws of the physics simulation. Whether or not a cannon or laser hits an enemy depends not on a dice roll but upon the trajectory of the shot and the size and speed of the enemy.

Damage is tracked module-by-module, and each module can be individually targeted & destroyed. Some modules can explode, causing collateral damage to the surrounding modules, so 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.

Single-Player

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 fleet, growing bigger and more powerful with every victory.

Explore a galaxy in search of bigger and more powerful enemies. The galaxy will crumble before your almighty armada!

Or play in a creative sandbox mode with unlimited credits if being a bounty hunter isn't your cup of Earl Grey—the only limit is your imagination! (And the power of your computer.)


Multiplayer

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 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.

It's easy to share your ship designs with friends and other players. Ships are saved as simple PNG image files and can be easily shared on social media like Twitter, Discord, and the official forums—just drag-and-drop the image from your browser right into Cosmoteer and the ship will be instantly playable!

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

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.

Cosmoteer update 0.14.13 is now available for download! This is a relatively small quality-of-life update that improves multiplayer latency (by adding support for "peer-to-peer" networking), adds an "auto" mode to Tractor Beams, tweaks mine balance, and fixes a handful of bugs.

What's New

Peer-to-Peer Networking

Prior to this latest update, playing Cosmoteer online (i.e., on a server as opposed to on a L.A.N.) required all network communications between players' computers to be routed through the server. This meant that every ship command, every gameplay update, every chat message, had to first be sent to the server, which would then forward the message to the other players. This basically worked, but created a lot of network latency (long response times to player commands) for players that were located far from the server (which is in New York, USA). For example, imagine two players in Sydney, Australia wanting to play multiplayer with each other: All of their network communications would have to travel halfway around the world to New York before coming right back to Sydney, which added a huge amount to their network latency. Wouldn't it be better if those player's computers just talked directly to each other?

It would! This is where "peer-to-peer" networking comes in: Instead of routing all network communications through the server, all the server does is help setup a direct connection between the host of the game and all the other players in it. If the players are close to each other or far from the server, this can greatly reduce latency and make multiplayer a better experience for everyone in the game!

For the most part this "just works" and you don't have to think about it at all. In some cases a peer-to-peer connection might not be able to be established, such as if you're playing on a restrictive school, work, or mobile network, or you have an unusually restrictive router. But even if a peer-to-peer connection can't be established, that won't stop you from playing, it will just mean that the network communications need to be sent through the server and you may experience more latency.

I am aware that some players may be wary of doing anything that could reveal their I.P. address to other players (especially streamers and others who may be at high risk for things like DDOS attacks and doxing). For that reason, there is also an option under the multiplayer settings to turn off peer-to-peer networking, which will force all network communications to be routed through the game server.

Multiplayer Game Searching, Sorting, & Filtering

Since multiplayer support was added to Creative Mode in the previous update, the number of multiplayer games has nearly tripled! This is awesome, but it also makes finding the ideal game for you a bit more challenging!

And so, by popular request, this new update adds the ability to search, sort, and filter the list of multiplayer games. Typing in the search box will hide any games whose game name or host name don't match what you typed. You can also sort the list of games by various things like open status, ping, and credits. And you can filter the list of games, hiding those that are closed or don't match the desired game mode, credit range, or ping.

Tractor Beam "Auto" Mode

Another commonly-requested feature was the ability to tell a tractor beam to automatically push or pull to keep the other ship at the desired distance. You can now do that! Selecting a Tractor Beam and clicking its mode button will now display a 3rd "auto" option:

When this option is chosen, the Tractor Beam will attempt to keep the targeted ship at a specific distance, automatically switching to pull when the target is too far and switching to push when it is too near. The actual distance it tries to maintain is whatever distance you set when attacking or following the ship. (If you target the tractor beam on a ship that you aren't attacking or following, it will default to a distance of 125 meters.)

Improved Mines

"Mines need a buff!", you say! I hear you loud and clear! And so they've received one: Mines now release twice the number of shrapnel, which now also flies twice as far, making it harder to avoid them:

... And more!

This update also has a number of other fixes and minor improvements, which you can read about in the changelog.

Have fun!

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
