Hmm... Is there a single player version of the game too?
That's exactly what I'm working on at the moment.
I already implemented to 75% the Singleplayer Mode:
Alien Massacre
You choose a hero and then kill everything you encounter.
If you reached an preset amount of alien kills, you have won.
There's also a timer which shows the time you already played.
Depending on how much time you needed and now often you died, you get a final score, so you can compare your result with friends.
What I also plan for Singleplayer is:
Survival Mode:
There will be waves of monster spawns, every wave becomes more difficult and stronger.
The longer you survive, the higher is your final score.
Maybe I will implement some kind of building ability so you can build barricades.
But what do you think?
For those modes, shall I remove the Alien heroes and just take the marines, but then add more marine heroes?
RPG Mode:
You have to fulfill random quests on the space station to survive.
(e.g. repairing the power generator, turn on the air control, fight against big bosses)
Bases for those events will be events of Dead Space 1.
(And maybe Dead Space 2 if my friend gives me his game

)
For this game mode I will use only human heroes.
