Replaying through Lost Planet on the hardest difficulty.
This is murder. MURDER. I've passed Halo 3 on Legendary, and CoD4 on Veteran, and even Dead Space on the hard difficulty. But this... this is ridiculous. No T-GEN regenerating stations, every small fight with akrids turns into a monster party where every single giant monster is invited. You can barely move because the character keeps getting blasted down by rockets or Akrid attacks. I'm out of ammo by half the level, and sometimes you have to complete a boss fight with no Mech. Impossible, I say. Impossible.
