PixelJunk Shooter 2 is hard. The first PJ Shooter I don't remember being hard at all. Right now I die a lot and a lot of it is trial and error before I learn what I need to do in a level to not kill anyone and survive myself. Thankfully the checkpoints are good though.
Also I can never seem to find all gems on my first try. I usually get 13/15 gems, but I always get all 35/35 survivors. If I accidentally kill one I'll purposely die to reset the checkpoint.
Can't wait to play the Dead Space 2 Severed DLC later tonight. Took too long to download for me to start playing last night. One of the trophies is to beat the DLC on Zealot mode. Thankfully nothing for beating it on Hardcore mode!
