Every Stage you start (almost) from scratch and can massively influence your round by selecting one of 3 random perks upon each level up. Weapons, powerups (limited time) and abilites (limited uses) drop randomly over the map. The game has a great pacing in introducing new perks, weapons and abilites. In general the game is quite fast paced and you have to be using the enviroment a lot. Mere DPS is not the thing that will just run you through this every stage. Select Perks smart, quickly plan your paths and be aware of your surroundings at all times. It is massive fun to play and so far the best Twin-Stick Shooter I have encountered. I can whole-heartedly recommend this game. (I have had no opportunity to check out Coop, yet. But I am guessing it is great, too.)
