The host runs this on a local server to run all these scripts.
Here's a summary of what they do:
• Choose between 3 SPECIAL WEAPONS (You can't have all 3 active!)
- Laser Grenade Launcher (Rebounds off walls, high damage to all including yourself/allies)
- Gravity Gun [Grenade Launcher] (Left to Launch, Right to Grab! Even survivors!) Carry an incapacitated or regret having this active since it's easily exploitative
- Sentry M60 (Firing a M60 now places the M60 as a sentry that auto targets! Don't want sentry mode? Time !

• SMGs (Silenced SMG, Uzi, MP5) are now Secondary weapons (Infinite ammo, lower clip size, lower damage)
• AWP is more powerful but has a small mag size
• Type !faint in chat to ragdoll mode! You can move, you cannot attack, you can still be attacked
• Visible displays of when a player is gaining losing karma within the L4D's hidden system!

Bonus: You can kill Zoey/Francis by shooting them at the start of the "The Passing" chapter
