Team up and take down the terror together - Play the full campaign in online co-op or single-player.Overcome avalanches, treacherous ice climbs, violent wilderness, and an army of deadlier, more evolved enemies on your mission to save mankind from the impending apocalypse. And Necromorphs are just one of many enemies they’ll face this time around. Comb the harsh environment for raw materials and scavenge parts to create the ultimate customized weapons and survival tools - you’ll need them if Isaac and Carver hope to make it off the planet alive. John Carver to discover and destroy the source of the Necromorph outbreak.

Also, I'd recommend doing this mode solo so you will not have to stress about someone else messing up.Journey across space to the icy planet of Tau Volantis with Isaac Clarke and Sgt. Know where the insta-deaths are, how to avoid them and it'll be a piece of cake. Ammo and health packs are plentiful, but making sure you have crowd control weapons, mainly against Feeders and Twitchers, is vital. Anyway, the key for beating Hardcore mode is knowing what to expect in every room.

However, I was at chapter 14 on Hardcore when I beat Pure Survival with my buddy, but I digress. Hardcore: I recommend playing the other two modes first before doing this because the rewards from Pure Survival carry over. Also, having a co-op buddy for this mode makes it a whole lot easier. Pure Survival: You'll get an excess of parts throughout the campaign and you will end up with more than gel and scrap metal to craft clips, health packs and upgrade your rig. It'll make the mode much simpler and the carbine isn't bad either with upgrade circuits so the mode isn't too difficult overall.

Classic Mode: If you got the limited edition than the Evangelizer shotgun will be your best friend.
