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
