You can't have the same weapon type in your loadout. I tried to do that for snipers when playing in Danger Zone but it didn't work.

You can switch weapons before respawning.

Thats what I thought, so if the is person has an AWP AND the stark vanquisher it must be some kind of cheat right?

If they have two sniper rifles in their loadout simultaneously that would appear to indicate a hack. The problem, as Sax alluded to is that you have to be certain that they have not died and changed loadout in-between. I have seen a lot of hackers lately but I have not noticed anything like this. Even if possible, I really don't see what benefit it would offer.

Yes, I stayed in the window with the loadout and status and watched the switching back and forth without being dead. Registered kills at the same time. The stark vanquisher was being used with an aimbot without a doubt, the AWP didnt seem like it. I watched it for a couple of games before i was certain. Not sure how its done but it was there, thats why I asked. Interesting.....

When I would get in close they would try a no scope with the AWP then after one or two shots switch the the SV and score the hits every shot

Definitely fishy. I have encountered what appeared to be an aimbot very recently: one-hit kills with a melee weapon, no opponent in sight. Been a long time since I saw something like that in Uberstrike. Back in 2011 you would find those guys standing on their spawn point swiping/shooting in all directions and killing opponents all over the map. Was that what you saw?
