Well I've played 2+ hours and it's really growing on me. I struggled with the controls at first but once you know what your doing K+M are probaly the best way to play.
The game is a more strategic version of '
Infested Planet' in an isometric view with polished graphics and nice effects.
The campaign can be played solo or co-op, where you select a zone and complete procedurally generated missions. Each zone has planets that range in difficulty and offer rewards ranging from bonus XP, supplies and other shiny things. It is repetative, your basically doing the same thing over and over but as you rank up and unlock new goodies the enemies grow in size and variation plus it gets hard!!
One thing is for sure, you can't just go into all missions guns blazing as you have limited ammo, turrets, revives, air strikes etc etc plus if your in a multiplayer game drops can splatter your team mates, turrets can also rip them apart plus there is friendly fire which cannot be turned off
