A top down shooter with AI that spawn around the map and try to defeat each other.
Your job is to push the "point" (that being the turf that your "team" has) forwards until the other team loses.
There will be different waves, with upgrades and new guns that you can find on the floor/purchase.
I'm thinking about MAYBE making it multiplayer (as in you can connect to servers and play with others online) but I'm not sure that it's really a good idea to add that for a game jam lol.
