This is called server hoping, it existed back in the mod as well. They will likely implement systems to prevent this in the future. The game is still in the early alpha stage so having players do this may be somewhat beneficial right now. It allows people to test rare items more often to ensure they are working properly. However later on this will likely be addressed.

I have yet to see any magazines for the MNX45. I have seen several of the guns, lots of ammunition, but no magazines. Not sure if they haven't been added or if i'm just really unlucky though.

Also when holding the FNX45 you can not manually chamber a cartridge like you can the Mosin and the M4. This makes it entirely useless without a magazine.

I can confirm this issue is driver related. I had the same issue where most textures showed as a bunch of squares of random colors. I am running a 7870, I updated my drivers to be sure it wasn't a game related issue and it worked.

If you experience this issue make sure you update your drivers to the latest version.

An anti-cheat system needs to be implemented. The main purpose of both the Alpha and Beta stages is to test the features of the game to insure they are working properly. With the scripts that have been created testing has become impossible in multiplier. Most servers that I join are hit within 3 minutes. This is a critical issue that I hope will be resolved swiftly so that we may get back to testing and reporting real issues.

The miniguns do have way to much spread. This issue needs to be resolved. When you can't hit a man from 30 meters away with a weapon effective past 300 something is wrong.
