Loot Boxes
v1.2

About:

I love the chaos, for me one of the funniest things of this game is to join a server full of shots, zombies, explosions and screams, the more confusing and chaotic the game, the better. I wanted to create a server of this caracteristics, so a lot of my plugins are focused on this, more zombies, more weapons, harder game... This was the first plugin that I started to make, even before publishing anything on this forum. However it was buggy and crashed sometimes the server, so I wrote the code again from scratch preventing any code error and server crash and I added a lot of optimizations.

Description:

• Special infected can drop a Loot Box when killed.
• Tanks and Witches can spawn multiple Loot Boxes.
• When a Loot Box is opened it can trigger a good or a bad event.
• Up to 34 different events.
• Boosts and nerfs for survivors who open the box.
• Global events that affect the whole game.
