+This plugin will automatically spawn an extra amount of tanks (determined by `l4d2_eft_count` cvar) after the second tank stage in a finale is over.
+* **Convars:**
+  * `l4d2_eft_count <#>` - Default is 1, determines how many tanks that are allowed to spawn in the extra tank stage
+  * `l4d2_eft_chance <0.0-1.0> - Default is 0.0, determines the chance of each tank spawning in extra tank stage.
+    * If the spawn fails, it will still count as a spawn, the percentage is PER tank
