Spider-Man Web of Shadows

As the achievements says you have to complete the game with any outcome. with the last boos fight against venom it is all about timing and web strikes press Y at a head that's lunged forward then press X right before your feet reach him you'll have to punch four heads 3 times each. Achievement will unlock at the end of the cutscene.

The best strategy to fight the 5 heads venom is simply swing around and when a head attacks give it a web attack (Y,then B), and then keep swinging.

I know its a little coward, but it works
