Obtenir plus de Plasm
Pour obtenir plus de points "Plasm" à chaque meurtre, frappez autant de fois que possible. Plus vous touchez consécutivement, plus vous infligez de dégâts et plus vous obtenez de plasme à chaque meurtre... ce qui signifie essentiellement plus de bonus, plus rapidement.
Beat final boss
When fighting Paavo for the final time, it can be a bit tricky. When he shoots at you, you need to push the white button according to the color he shot at you with. If its red, use stealth and disappear. If its purple, block with the sword form. If its blue, absorb with the gun form. When you see his little wing things fold in, you will see a time dialation marker around Paavo. Attack with time dialation. It will appear the same way when you interface with a node. When it appears you will strike the final blow, it will say interrupted. You will then fight Paavo hand to hand. Just beat him the way you beat him the first two times. Then, you both will float, and play Pong death match style. Just push "B" when the energy ball gets close enough. It gets really fast so be careful. One hit will kill you. After you finish that and Paavo falls, then sit back and watch the time dialation finish, and the ultimate butt kicking begin.
