Strike force heroes made by the same people who made raze. As far as I can tell it is pretty modern. It is a 2d action shooter with platformer elements. It has four classes, the medic (ARs and "magnums"), the assassin (snipers and melee), the commando (lmg/hmg and grenade
lawnchairs. launchers), and the "tank" ( Shotty's and shields.)
They all have the same basic secondaries, pistols and smgs.
