-For the challenge just stick to the right of the screen when it gets to the tough part.
-For the final boss just focus on getting the main streams of people he drops, you need 3 of those.
-For the easy badge just kill every single man without saving a single one
Fun game, my only complaint is introducing those death star things in the last couple of levels.
Had no idea i could die in this game and getting killed out of nowhere that late in the game was just annoying.
For everyone else: Needing to conserve your ammo is the whole point of this game, you dont always need to be shooting :/ lol
