Last night I found a SEVA suit in Yantar that totally rocks. Ain't no fire, lightening or radiation that's gonna kill me.  I love how there were many spots that I could not get past in the early stages of the game that are now going to be accessible to me... it's an awesome Metroid style of game design that keeps me coming back for more and more. Add in my multiple Endurance artifacts and I can now run non-stop forever through the zombie wastelands. Take THAT Pseudodog!
