Invincible Tank Survival [ITS] is a gamemode invented by a friend and I. It started out by hosting survival, but only letting invincible tanks spawn. This turned out to be a whole lot more fun than regular survival.
Throwables have been given some new purposes.
At the end of the round, the game will provide fun facts about how it all turned out.

RULES
IN CAMPAIGN (VERSUS): The last man standing wins! No helping your teammates, it's all about you surviving longer than them!
IN CAMPAIGN (CO-OP): See how long you can make it as a team!
IN CAMPAIGN (SPEEDRUN): Run to the safe room as fast as possible! Invincible tanks are chasing you!
IN VERSUS: Get the highest score as a team!

HOW TO PLAY
Enable its (its_enable 1) and start up any finale map (mall finale, hard rain finale, passing finale etc.). You will notice there's a lack of common infected. Once you start the finale, tanks will spawn at a certain frequency, and it's all about staying alive!

THE THROWABLES
Molotov
Slows down tanks for 15 seconds.
Pipebomb
Explodes on impact. Stuns tanks depending on how well it hit but you can also risk stunning yourself!
Boomer Bile
Confuses tanks!

ConVars
its_enable (1): Enable Invincible Tank Survival (0: Disable, 1: Enable)
its_info (2): Number of times to show info message. 0 to disable.
its_frequency (25.0): Time in seconds between each forced tank spawn. If 0, no additional tanks will spawn.
its_burn_time (15.0): Time in seconds until the tank is extinguished and his speed recovered.
its_burn_speed (0.75): Burn speed penalty (relative).
its_stun (2): Stun method. 0 = none, 1 = everyone (including teammates), 2 = yourself and enemies, 3 = enemies only.
its_boom_bug (0.2): Interval between bugging while boomer biled. 0 for none.
its_boom_strength_bot (6.0): Bugging strength on bots. Should be more than for human players. 0 disables.
its_boom_strength_survivor ( 0.1 ): Bugging strength on players. 0 disables.
its_version: Current plugin version.

Commands
!mode (in chat): Vote for a new campaign gamemode.

Seems like an interesting idea. I'd try it out if I still had my own L4D/2 server

[JoeInky]

If you're interested in playing it we'll be getting an ITS server for L4D2 soon.

If you join the group you'll get announcements for when new ITS maps come out and when we're going to be playing them.

I'm the friend that helped create it by the way just incase I look like some random person.

This would be better with tank's speed boost for every X seconds...

more tanks spawn as time goes on, when there's 14 tanks I'm sure you wouldn't want them to have a speed boost

There are a few bugs with this plugin.
1) Common infected sometimes are able to spawn on the 1st load of a finale. (next run is fine)
2) Tanks 2 and 3 sometimes spawn simultaneously.
3) Tanks die immediately upon spawn during the Bridge finale.

I like the running timer on the message pop up, but the renders weapon switching with default keys, useless. (Forced to use mouse wheel to switch)

Request: Optional setting for tank health, for those who would like to work together and bring down a few tanks. Some info on total damage taken by all tanks.

1) Yes, but this only happens if you start it with its_enable 0, then turn it on. I dunno if I'm able to loop through all existing common infected and then remove them since they don't act as players, but I'll give it a try!
2) Only on maps that force spawn (such as the Dark Carnival finale)
3) The bridge finale uses a special finale start hook that I've been unable to find. So the finale is never actually started and as such any unintended tanks are killed. If someone finds the hook out I'll gladly add it

and the running timer is a known problem, I'm currently looking into alternatives!
