Couple problems I have with the SWEP:
[list] With a large group of NPC's, a few will still shoot you.[*] Right now I'm playing with it, and while I'm still cloaked, I get the message that says I can cloak myself again.[*] I haven't tested this 100% because of the reason above, but I'm pretty sure if you die shortly after becoming uncloaked, respawn, and equip the SWEP, you won't be able to turn it on until it "recharges"[*] You can use the 9mm pistol while cloaked.[/list]
I know, there are some bugs, cause of timers. I wish I can fix them soon.
P.S.: Oh and sorry about "cloack". My mistake :O
