Soldner-X: Himmelssturmer

It’s best to get this trophy on Beginner and on the first world. If you do that, you’ll have to survive almost all of the way through the jungle for this trophy.

Below are two methods for getting this on the first boss very easily.

Fierce Fighter is easy to get use a second credit. Fight to the Boss and destroy his cannons. After this just go down in the left corner and wait a bit. Your time will run away and the second credit is used to get the trophy. Wait 5 Minutes and the trophy appears.

This trophy isn't all that hard. When you get to the first sub-boss, take your time killing it (but make sure you do, as it drops a multi-shot power-up). It's a very easy sub-boss to avoid, as it's quite slow moving. I took my time killing it, that helps rack up the seconds. And then when I was about 30 seconds into the jungle, the trophy popped up .
