The problem with this attack is that after he lands it will crash down some boulders which will do considerable damage if you don't warp away in time.
Those guys are only dangerous if you see them carrying a grenade instead of a knife since they will suicide in an explosion that damages you a lot! His jump attack is lethal in close quarters, but easy to dodge since he mostly jumps away from you. The first will be a vomit attack which will damage you if you are right in front of him and also spawns zombie soldiers. This is a pretty easy enemy since he can't block and he only has a limited set of attacks.
Now run through and you will encounter your first boss, which will be a big zombie-like creature called "Goreface". Basically you have to get the hammer like weapon (for Sooki it's the cloud sword, a big cleaver) to destroy the force field generator. So we start on "Lunar Wastes" and there are plenty of arrows that will guide you to where you have to go. So i started with The Dishwasher since he was the character of the first game and I sort of felt familiar with him. Since the levels are quite linear and there are arrows showing you the right directions, I won't go into much detail on the levels themselves and will focus on the bosses and best tactics against them. So with that said, let's get down to bloody business!
I will also go into detail on how to beat certain bosses and which tactics are the most effective ones. I also recommend getting all of the ghost beads on the first playthrough since it will spare you a lot of work on the "Samurai" difficulty. You can unlock all of the story achievements in coop as well and I can say it will get considerably easier with 2 players instead of 1.
You only need to play through the game once on "Samurai" and you unlock it automatically as soon as you finished the story once so either play on "Pretty Princess" (will be explained a little bit down below how to unlock it) or "Easy" if you want to finish it as fast as possible. It will also show you the moves of the enemies you will encounter and since you certainly will need 3 story playthroughs, it's better to get it over with fast. It's totally up to you as to which one you choose first but I, however, recommend the story mode first since it gives you a basic idea of the controls of the game AND how to use each weapon. Alright, I will separate this walkthrough into 2 parts which will be the story mode and the arcade mode.
