I have that map. It's a pretty good map at the start. It get's a bit crappy though. I downloaded some stealth character and in the part where there are 2 snipers followed by a drone thing (forgot the name) guarding the door. There is a little ditch between the crates and I had just enough stealth battery left to get in there and hide whilst it recharged.
Then I took aim with my pistol and knocked out on guard then I used an EMP grenade to knock out the drone then hit it with my silenced MG then I used my silenced pistol and took out the other sniper. It was a good day for me. I got right up to the door before the brain room and I fell down but apparently my weapon (C4) wasn't stealthed and got caught, I throw the C4 on the drone whipped out the detonator and it got shot and broke so I tried to take it down with my MG but it shot my helmet thing off then headshotted me and I died. :sad.gif:
