Every 15 seconds and each time you earn an elimination or die, you will receive a random effect.

Over 150 possible effects!
Gain stat upgrades such as increased damage and speed
Increase your maximum health with armor, shields, and overhealth
Gain temporary powerful abilities such as invisibility and aimbot
Be teleported around and randomly explode
Gain your ultimate instantly or have no cooldowns for a few seconds
Swap to a new hero every time you die, but keep your ultimate charge
Highly customizable settings
And much more!

In the top left of the screen, you can see the latest effect that you received as well as any temporary effects you have and how long they will last for. Green is generally an upgrade, red is usually a negative effect, purple is a special ability, and yellow is a stat reset.

In the top right of the screen, you can see your current stats (damage, speed, gravity, size, health, and knockback).
(The health stat refers only to maximum health and does not include additional health such as armor or shields)

If you get stuck, hold crouch and interact to respawn.

This is a variant of my Chaos Randomizer Deathmatch code (WGR12) that works with normal gamemodes like control. Some effects and mechanics were changed for balance.

You can edit the duration of effects and customize other settings in the workshop settings tab.

This mode is absolutely not supposed to be taken seriously. You can make a lot of cool plays, but you will also die stupidly. A lot. Just relax and have fun!

Known Bugs

The 'Burn Your Enemies!' effect will stack with itself, ensuring that anyone hit while the ability is active will be killed.
- This is kinda funny and makes the effect somewhat unique but I might fix it eventually if it proves to be too broken (it definitely is on workshop island/chamber since you can kill everyone in a very short time).
Players will often get stuck in certain rooms if they are too big to fit through doors.
- This is the main reason why the crouch + interact to respawn feature was added. This generally only happens when playing a tank hero at 2x size. Most of the time, you can crouch to fit through the door.
Switching players' teams while the game is active will crash the server.

Let me know if you have any suggestions for improvements or new effects!
