me and my friends are gonna make a space game it will be a 3d monster hunter game i will be posting concept pics of the monsters and a stage map of the first level we are just decideing on the final details then i will add more detail please tell me if you have any ideas on what could happen like end of the level you get sucked out of the airlock

we have not decided on a scoring system so that would be helpfull if you would say what kind of system and if it will be a zerg game (lots of low level monsters attacking permantly) or a heirachy system (minions and end boss)
