The Amazing Spiderman - How to get easy XP
In The Amazing Spider-Man for PS3 and Xbox 360 there is an easy way to level up and earn XP to unlock new skills.
In the mission "Oscorp is your friend" in the first chapter, you will have to face the first S-01. Killing an S-01 will earn you 2.000 experience points and 150 tech points. It takes a couple of minutes to beat one, and considering that you can save the game, reload and repeat as many times as you want, in half an hour you can earn around 25.000 XP.
It requires some patience, but it is certainly very effective as a method.
