the more scientists you have the more items will spawn.
each tile has a scientist so you obtain more tiles to prepare for the fight.
have 10 scientists and item spawn becomes too fast. and bombs start blowing up your own tiles
barracks produce 1 troop spawn and it goes away if you dont put it on a tile.
doesnt produce after that.
you can only attack with nukes so make sure you have enough nukes and troops ready before you attack on enemies.
in the sudden death event which is triggered by leaderboards resetting if you are alive on the map you will be granted access to the profile upgrades shop where you buy skin upgrades etc. but sadly the shop didn't make it in time for jam so for now you are just celebrated for survival. :(
thanks for playing :) i hope i can make more likeable games in the future.
