I too have the problem with the invalidated HD.
The Sniper Rifle sucks, it has to low damage against other cyborgs.
And to clear atlantis you need lots of gauss guns, and save one shot for that last wacky guy in the house at the end. Also you'll need at lest one flame thrower, stand behind a corner with and just wait for the enemies to run into your lovley little flames :-)
Fill out the rest of the weapons slots with miniguns.
Also you could also have energushield on all chars and work with them one at a time. If you just manages to get thru the initial onslaught you shold be able too handle the rest, but you will run very llow on ammo no matter what you do.
btw I always liked the shotgun up close and the lazer is an awsome sniper rifle ;-) altough you could just snipe them with the gauss gun :-)
whooa my biggest post this year :-)
