X-Men Origins Wolverine - 46/51 trophies
Light 20 enemies on fire
There aren't a lot of places where you can do this, so you have to go out of your way. The last jungle level has flaming enemies with machetes, so I let myself be hit by their jump attack to set Wolverine on fire, then grab the smaller enemies around the area while on fire to pass the fire on to them. Next up, replay levels a bunch to grind total kills and specific enemy types.
Call from demon - with dark power to tempt your mind, very proud of the power. Destroy the firing shot!
