Fusion has multiple official Gamemodes which you can add support for in your maps. Some require specific scripts, while others will work automatically.

Deathmatch, Team Deathmatch, Juggernaut

A necessity for these Gamemodes are specific Gamemode Markers. These act as the spawn points for players upon death. More information about Gamemode Markers is on the wiki.

Also, for items to be able to despawn and respawn upon Gamemode start/stop, Gamemode Crate Spawners are extremely important. More information about Gamemode Crate Spawners is on the wiki.

Entangled, Hide and Seek

No extra scripts are required for these Gamemodes!

Smash Bones

A necessity for Smash Bones are teamless Gamemode Markers. These act as the random spawn points for players on Gamemode start as well as upon death. Also, Spectator Gamemode Markers are important for contestants who have run out of stocks to respawn in a Spectator room. More information about Gamemode Markers is on the wiki.

Also, Smash Bones maps typically have items dropping from the sky for players to use in combat. To add these, you must add Gamemode Droppers, and optionally Gamemode Dropper Settings. More information about Gamemode Droppers is on the wiki.

Finally, for players to properly die when flying out of bounds, you must add Death Triggers. It is recommended for Death Triggers to encompass the floor, walls, and sky of a Smash Bones level. More information about Death Triggers is on the wiki.
