Level 1: Soft Landing
Difficulty: Easy
Like every other game the first level is all about getting used to the controls. I'm playing on Easy, because the game can be quite difficult on the other setting.
There are a few areas where it can be kinda tricky to get through at first.
The sub-machinegun wielding soldier which you encounter after a while is one of the enemies that is all about dodging by jumping at the right moment.
Then there's a part where you have to destroy a gunship. Safe all your sub-machinegun ammo for this "miniboss" because the faster you destroy it the less you have to worry about enemy reinforcements.
At last theres a tricky jump right after the fight. Take your time and you should be fine.
