Gunborg: Dark Matters - 100% Trophies in 40 Minutes
An arcade-style 2D platformer that has you play a lady with a sword. You can triple jump and pick up guns off enemies you kill, and also have a shield to block attacks with.
The 100% involves beating the game, S-ranking every stage, and getting all infobots, which are very easy to find.
It's advised to play on Normal to make getting S-ranks easier, while not making the stages too difficult. It's recommended to play the final 3 levels on Hardcore, as they're just surviving multiple waves of enemies, and Hardcore makes the stages easier to beat, since more powerful enemies will appear and will have more powerful guns for you to use.
S-ranks are based on a point system that awards you more points if you don't get hit a lot, finish the stage quickly, collect all infobots, and kill enemies in succession without getting hit. The last one is key, as doing so will build up a combo multiplier up to 3x score. It'll also grant you dark energy, which strengthens all attacks as long as you don't get hit or wait too long in between kills.
