Pros:

The entire look of the AK12 is just perfect. It matches the game perfectly. I have no other words to say.

This gun looks mean and sounds mean.

The reloading animation couldn't get any better! I love it!

The flashlight is correctly positioned. Extra brownie points!

Cons:

Firing on full automatic makes it look like that the gun kicks too much (the barrel still fires when its raised). My suggestion for the fix is to reduce the kick a little.

Conclusion:

Never thought I'd see the day that I'll be pleased with a Weapon mod entirely. This AK12 mod has met all of my expectations. If you're looking for a perfect AK47 replacement mod, then look no further.

Pros:

This P90 sports a very cool custom skin! It looks aesthetically pleasing as the texture used to wrap the entire gun fits the setting of the game nicely.

The tactical features placed onto the gun is accurately depicted from its real life counter-parts, so extra brownie points for that.

The reload animation is fluid and standard. I also notice that the case itself is see through, good job on making it look very accurate!

The lens on the gun looks very nice as decoration, although I would've preferred it to be functional but hey, there's no ADS in L4D2.

When idle, the gun swaying looks very cool. No other comments for that!

Cons:

This silenced P90 makes an awful lot of noise for a suppressed weapon.

It's also generating a lot of muzzle flash for a suppressed weapon (which is supposed to reduce it or eliminate it altogether).

Conclusion:

A great mod! I still am using it and am very pleased to say that I am loving it. There's not a lot of good mods like this out there.

Pros:

The G36C replacement mod has met good expectations for people looking for a particular alternative to the M16 rifle. 

The textures used for the rifle has remained true to the zombie apocalypse setting, giving it a nice look both underneath lighting or when in complete darkness. 

Its tactical features such as the flashlight and the laser dot placement is also well-placed. 

The reloading animation is fluid and well-thought out, making it unique than your typical 'pull mag out and load another in'. 

Rapid fire animation is consistent and everything looks very very aesthetic!

Cons:

First person animation of the gun makes it look like you are constantly sprinting. While minor, perhaps I would've prefer a more subtle swaying of the rifle.

While the animation is consistent when firing at full automatic, the barrel alignment and bullet flight path do not match in a straight line to the reticule. It seems like the bullet travels 10 degrees to the left out of the barrel when shot.

The gun fire sound however is oddly very out of place. It sounds quieter than other vanilla rifles. I had expected a beefier, louder gun fire as you would expect from a rifle with a standard 5.56x45mm bullet (which the M16 has too).

Conclusion:

The entire rifle looks very pleasing for those people looking for a HD textured replacement of the game's vanilla M16. It looks very practical and sensible in terms of realism.
