Random round modifier
This plugin runs on SourceMod and is only for TF2.
This plugin will pick a random modifier(sub-plugin) and a random value for that modifier for each round. The possibilities are endless and every round will have a unique twist.
What are modifiers? They modify/add certain effects on every player on server to make the round different and more fun.
For example, one of the modifiers is called Random Head-shot explosion. The first round could make all head shots create an explosion. The second round could make melee damage increase to 350%. The third round could increase everyone speed to 150%. It's all random!
There can only be 1 active modifier per round. And will work for any map. You can also write your own modifier!
