Tank Oppressor Trophy
Destroy 20 tanks in sequence.
You can get this in the first level of the second world 'Claustrophobia'. The level has two sides but don't worry about it right now. For this trophy you need to destroy 20 tanks in a row without killing anything else so when you start the level, go to the left where the tanks come out of the two holes. Just destroy them every time they come up, but be sure to dodge the turret thing that will appear behind you as it shoots missiles. Once you rack up 20 the trophy is yours.
