Mana Pool: This is an FPS from the people who invented the genre. It is of impeccable lineage. I think if you look at its birth certificate, its full name would have more double-barrels than the bargain bin in a shotgun superstore. Anyone who’s played an Id game will know something of what to expect. Stunning visuals, smooth gameplay littered with gore and shock, and monstrous bosses with ridiculous guns. Anyone who hasn’t played an Id game is lying, or a doppelgänger that must be slain.
