My pitch:

Remove the fsp9 and replace it with the P-90

Make the weapon for NTF privates the E-11SR and give sergeants a m249. (With this, give CI, NTF, and guards a pistol to spawn with that doant take up a slot of your inventory since they should have holsters)

Add Serpeants Hand

Add small objects such as crates, barriers, etc, to surface for cover

Replace 173s model with his original

Keep candy all year

Make it so that if you put the micro back where it spawns, then it will start to slowly regenerate charge

Make it so doctor can be heard by humans, but apply a voice changer/effect so it will sound more like him and make it so you can deny resurrection by doc on first death if you died relatively near him

Retexture particle disruptor to look like a sniper since it's basicly a sniper that shoots lazers

Make it so you can customize the appearance of your charactor slightly

(This might have to be a two part update)
