When I play the SP campaign in Crysis 1 I use a custom 'Delta' config. The original was created by Doomlord or Solocist (apologies if I mis-spell names here)with me tweaking it to my liking. Now i know it's a while off from the SDK but I wondered if anyone had found a way to spice things up a little?

There is a mod that make the game almost impossible, try to search it in Cry Mod.
