Shadow Warrior 2 sure is something. I'm really in love with the quick slash mechanic, and the Samurai Jack-esque physics. Basically, if you switch to a melee weapon while an enemy is in melee range, you turn the draw into a slash. I was unloading my gun into a large bipedal enemy that was running at me, it jumped to hit me, and I dashed sideways while pulling my sword out. Seems I'd inadvertently done the quick slash during the dash because the enemy was suspended in the air in two perfect halves.
Yeah, the physics engine tries to mimic bad anime decapitations.
