The NeuroGen Incident

After four months of hard work, today we are massively proud to announce that our very first full co-op experience has been released!

Interstellar Marines is a game built on the promise of awesome co-op, and The NeuroGen Incident is the first time we've unleashed the full power of our co-op experience. Built in a level 6 times the size of our largest multiplayer map, The NeuroGen Incident allows you to play through one of the pivotal stories in the development of the Interstellar Marines program.

With difficulty levels ranging from Easy all the way to the legendary Interstellar Marines, The NeuroGen Incident can be played through multiple times with a different experience and path every game. You and your co-op friends will be fighting intelligent enemies, in different areas with divergent paths to success each time you fire up Interstellar Marines! We've even added several new Steam achievements for you to achieve during the fight.

Really can't wait for this. Looks awesome.

However, what do I not like is the hype machine you're trying to build. You buff your own games up so much it makes it suspicious. Your videos showcase an awesome looking game, fun and such, but there has been many games with a similar look, and feel, and gameplay based off the three demo's so far.

But your videos constantly state that it is very unique gameplay.

Ok Mister xalener,
no need to get nasty and personal.

This is a fps, right? So for an fps, the graphics are crucial. No one want's to play a shooter with ancient graphics from 2005. These guys trying hard to get the best out of Unity with post processing effects and shaders. That's great. But this is like you put a shiny icing on top of a poorly backed cake. Unity rendering capacities are pretty weak compared to UDK or Cry, when it comes to desktop games.
And what do you think how fast this will run in a Browser? I tried it and the performance was not really satisfying.
I'm not against Unity at all. Or this project. They doing a good job with the limited opportunities. And I'm happy to see when a small indie team compete against the big guys. Unity is also a nice tool for casual games and great for mobile games. I worked on some Unity games for iPhone as well.
But for an desktop/console fps, it is simply not the best choice. There are engines which are way more potent for such a graphics intense genre with optimized tools that suits perfectly for such a task.
Furthermore permit me to remark, that I find it really immature to get voted down and personally attacked just because I asked a simple question. I did not talk this project or Unity down. And I have no problem to discuss this as long we keep this in a decent manner. Ok?

That's a bit near-sighted, my friend. You need to expand your horizons. Many f2p games look like **** compared to this and do extremely well. Hell, CS is still played over the better-looking CS:S. It's not ALL about graphics.
With that said, I do think these guys have put a great effort into polish, which is way more important. Every piece looks like it received the tlc it needs. You are also vastly under-estimating Unity's potential. Not only is a great engine already, there are MAJOR engine upgrades coming in the next few months.
To correct some misinformation: The Browser player and Stand-alone code are practically identical, so it will run fine in either (and already does as evident in the bullseye and running man demos).

well it depends really, but btw i don't think it's possible to run unity on a console, but a good game dose not depends on it's graphics examples would include freespace 1&2, halo 1, homeworld, red alert 2, and tiberium sun, these are truly fantastic games all with horrible graphics compared to now but yet they live on. i rate games based on game play, re-playability, overall awesome, originality, and that's all i can think of right now but yeah it doesn't matter about the graphics, it's the game that matters and if you think otherwise your an idiot
