This game is just incredible. It takes the cheesy 40s aspects of Fallout and slaps them into a wild sci-fi plotline I haven't seen the likes of which in awhile. When you read all those reviews out there averaging 9/10, they're not kidding. This engine is the most innovative FPS jump since quake. You get to combine zany mad scientist weaponry and inject yourself with dna splicing plasmids to evolve your genome into magic casting capability. You literally walk around freezing or frying people with your mind, using telekinesis to thwart throw their grenades right back at them, shoot lightning into a puddle and zap all foes within it, the works. I'm now fully addicted. Mad science rules.
