Pros:

-Fully Automatic G18 surpressed.
-Nice Origins
-Texture quality is spot on

Cons:

-The Fireing animation has way too much recoil for it to be an automatic pistol
-Walk animation (Not too much of a con but considering most others have some decent walk animations you see in triple A titles these days it would be nice to see abit more wobble but still be aimable)

Conclusion:

Its a nice replacement for the surpressed Mac-10 which is default in L4D2 but its problems being that its recoil is based off that of a single shot and not designed around the fact that this is a fully automatic pistol. As such it looks like its aiming way off center in a full automatic cycle. It feels too odd to aim that way and detracts from some of its value but is still worth giving a shot. 

If any more automatic pistols are done in the future. i recommend abit more of a steady recoil animation. one that doesn't look as heavy on the hands.

Overall its an extremely attractive package for its minimal issues and is worth some very hefty praise. I may have a preference to other modelers animations but download this if you are looking for an SMG in a much smaller package.
