Rebirth is a survival horror sandbox game with a focus on procedural environments and dynamic AI. Influenced by games such as STALKER and Silent Hill, all set in a sandbox world ready for players to explore.


Scavenge. Hunt. Explore.


Fend off a group of survivors who found your house. Reinforce the barricades, check to make sure you have enough batteries for your flashlight.



Rebirth is a game about survival. The world is in shambles, shattered to the core due to a mix of mysterious events. The air is barely breathable, society has crumbled and governments have toppled. What will you do when your way of life no longer exists and strange beings roam the earth?Do you have the will to survive?


  • Procedurally generated world – There will be a large amount of buildings and places that are procedurally generated to keep gameplay fresh and interesting each time you play.
  • Living, breathing eco-system. AI with goals and advanced behaviours, such as actively searching for you when they lose sight of you, searching key locations for food, etc.
  • Emergent gameplay – Random events scattered throughout the world. Your house may be raided or attacked one day, or you may find a map leading you to a loot cache… or a trap!
  • Survival based gameplay – Scavenge during the day. Find food, weapons, medical supplies, ammo, and scavenge for shelter. Try to survive the night to see the light of the next day.
  • Procedural Horror, immersive atmosphere and dynamic scares!
  • Various enemy types, all with different behaviors and objectives. No “This Enemy is a bigger version of that guy who does more damage”. A core philosophy is to make each enemy have a role and be special in their own way.
  • Full body awareness.
  • Barricade existing buildings, set up defenses and generators using items you collect and the environment around you.
  • Meaningful death.
  • RPG elements – Your character can become more specialized as time passes and they get more experienced.
  • Mind-warping horror system. Your fear shapes the world around you…
  • Collect information and piece together the origins of the disaster.

Future planned features

  • Social game play dynamics: Your most dangerous enemy may be humanity itself. Will others help you, or hunt you?
  • Multiplayer – After most mechanics are complete.
  • Rebuild society and craft your own items and possibly buildings (later releases).
  • Completely procedurally generated environments

Let's start things off with a visual shall we?

He's dead Jim

So we have been quiet for a long time. What gives? Well mainly I have been working on the game a lot, as you can probably see, we've had quite a bit of an overhaul visually. I've also done quite a bit of footwork creating some really cool tech that we're going to be showing off in the near future, tech that will power a lot of Rebirth's systems.

Take melee for example.

I'm tired of FPS melee systems where you swing a thing in front of you and it does X damage. Aren't you? I like some interaction when I swing my pixels around the screen, and I personally need some depth if I'm expected to whack things over the head with a bit of copper tubing or what have you. I also want it to feel pretty satisfying.

I expect most gamers would agree with this point of view.

So I set out to create a melee system that meets a few key criteria:

  • Has depth
  • Is fun
  • Is interactive beyond left click and aim center of screen at guy
  • Is satisfying
  • Rewards skill

How does Rebirth's melee system rise to the challenge? Let's tackle that one by one.

It has Depth, Interactivity, Rewards skill

In Rebirth, we currently only have one weapon implemented, the trusty rusty machete. When designing the system, I tried to keep future expansion in mind, but first let me explain how the machete works.

The machete currently has 4 different attacks (mainly constrained by animations, which is why we don't have more yet). Each attack is performed based on the direction on the keyboard you press in combination with the mouse button. LMouse + forward performs a stab move. LMouse + left performs a backhand swing.

Why do you care which way you swing? Aren't they all the same?

No. Weapons in Rebirth (as well as enemy melee attacks) are physically simulated. This means that you only hit an enemy if your weapon actually makes contact with them. Each enemy also has a multitude of hotboxes on each body part, each having a different damage multiplier. Headshots do more damage, whereas body blows or limb blows do less.

If a monster swings its claw at you, they only hit you if that claw touches you. If it swings two claws, if only one claw hits you, you take 1/2 the damage you would have taken.

It's physically simulated

If you swing hits more than one body part, you do damage for each part you hit. Thus a long swing hitting multiple body parts does more damage than just clipping an arm.

But there's more to it than that.

In addition to that, the damage done by a melee weapon is fairly low. If someone pokes you with a stick accidentally, it's annoying right? But if someone stabs you with said stick, it really hurts, yes? What's the difference between a poke and a stab?


So in Rebirth melee weapons do damage as a function of the swing's velocity. If you manage to hit an enemy at high velocity, you very well could chop their head off in one blow, or cut them in half entirely. In fact, I've had a ton of fun running at full speed to charge an enemy, jumping up and then landing a blow as I come down on an enemy's head, chopping it clean off. I can't wait to let you all play around with it!

You want to know what else is physically simulated? Blocking.

You can block hits at any time with your weapon, but the success depends on how you catch the blow. Blocking with make an enemy recoil back but their claws are still deadly weapons so you can still take damage even if you block, if you are not careful about it. The block button (currently right click) brings up your weapon in a blocking stance, but it does not guarantee a successful block, that only happens if YOU make it happen.

It's fun and Satisfying

So if you add all of the above together, you get a fairly fun system. Then we add the dismemberment on top of that and you have a REALLY fun system. There's nothing as satisfying as blocking a hit, sever a head clean off, dodge to the side and have an enemy hit another enemy as they swing at where you used to be, then with a backhanded blow, sever both torsos clean off with your blade.

What's Next?

I'll probably do another dev diary about the melee system this time. The mechanics are cool to talk about on paper, but I really feel like it would be better explained on video. I'm also going to start being more active posting news and media since I feel like our art assets are finally at the standard we'd like to hit for Rebirth.

There's a lot cooler stuff coming soon, keep your eyes peeled and please tell your friends and the media about us!

Tracking. Survivial games are in the wind these days! Of the screenshots I could see, it looked real nice! Always fun to stumble across other unity devs too! Keep up the good work!

Thanks for tracking. Funny, we've been in development since early this year before the whole survival game craze started, before I'd even heard about any of them. Good timing I guess, I was really surprised to see how popular they've gotten, I was honestly expecting our type of game would fly under the radar well past release. The beauty of the indie scene I suppose.

Though by the time we're done, maybe people will be back into sci fi flight sims? New Wing Commander please?

Yeah who knows right :) Nothing to do but buckle down and make a good game that you'd want to play yourself imo, and then cross fingers that it'll sell when you're done.. haha. Looking forward to seeing more of Rebirth!

Hey there,

We are prototyping the game as singleplayer first, and once we feel the gameplay is right, we plan to implement multiplayer. No first person view yet, but if we feel it would improve the game we can easily add it later.

Sounds awesome cant wait for a release, my only question is are you planning to make this game a free to play?

Rico21745 Jul 9 2012, 12:35pm replied:

We aren't sure about that at this point, our goal right now is to make an awesome game, and then decide based on the work/quality of it what we'll do with it. I'd really like to alpha-fund it somehow, essentially taking a Minecraft approach where alpha funders get special perks and a significant discount for supporting us early on, and basically getting the full game for free after release.

Of course, this is all very much up in the air at this point. I've already sunk some money into the project, and all of us are putting in a lot of time, so I don't know how realistic free to play is, unless we had another revenue stream of some sort, like in-game purchases or ads.

We're open to ideas from the community though.

Doing a kickstarter or something on Indiegogo might work for you in that respect then. If you haven't heard of them before essentially people who are interested in a game (or other things like movies and such) can fund its development in return for "perks". There are different levels to the perks depending on how much the one funding the game contributes and each higher level of perk as far as I've seen includes the rewards for the lower tier perks as well as an additional reward. For instance you could have it where a person who contributes $10 would receive the game on release, someone who contributes $15 would receive the game + beta, and someone who contributes $20 would receive the game, beta, and alpha.

There are some differences between Kickstarter and Indiegogo, so if you are thinking about doing it I would look into both and see which one works best for what you are looking for. ^^

(Have to admit, I can't figure out why this appeared in reply to this comment and not the one where you were talking about possible funding methods and wanting to do a Minecraft-like alpha fund. I just joined these forums so that I could suggest Kickstarter or Indiegogo to you, so I'm still a noob at replying I guess. :P)

I think if you made it free to play you could have ad revenue and micro-transactions (anything from character skins to better gear if need be) or you could have a membership deal where members would have better gear than other people. but in saying that i would like to see it free for every one

Hey commanderbrowncow,

Sure, like I said, we are very open ended when it comes to what we do with the game when we release. I'm not sure how I feel about micro transactions, but regardless, just know that we will do our best to price our work right so that it is available to as many people as possible.

I hope its not one of those multiplayer games (when you add it in) where everyone buys stuff except for those few who can't and get owned by everyone else... Anyway, this game looks EPIC.

Nope, that's exactly why I don't like "free to play" games of that sort. Thanks for the comment!
