Survival of the Fittest is a stand-alone Multiplayer Online Survival Arena (MOSA) spin-off of ARK: Survival Evolved, initially launched as a total conversion mod and tournament with Patch 200, before eventually being launched as a stand-alone spin-off game on March 15, 2016.
With it's release Survival of the Fittest now allows Mod Makers to create complete and total conversions to the game. SotF changes the map to introduce more pure PVP elements as opposed to the basic vanilla map. Crafting and engrams are changed, resources and tools are limited and Dinos rain from the sky.
Players and Tribes must work together to be the last human(s) alive similar to the popular book/movie series The Hunger Games.

There were 35 teams of 2 competitors each, where the final tribe standing was awarded with a Grand Prized of $20,000 together with bonus gaming gear from Logitech and Gunnar Optiks! $10,000 and $5,000 will be sent for the second and third place.
