Random TDM is a pre-built Custom Match game variant. As the name would suggest, it is essentially a combination of Team Deathmatch and Randomnauts. Players are given a random 'Naut with random upgrades, and are placed in an arena. The goal is to reach the Frag limit. Players receive a new 'Naut on death.
As with all custom matches, Random TDM's settings can be tweaked to the host's liking.
