The Season Pass for Evolve doesn’t contain the over $130 worth of extra DLC available.
The grand total of all DLC listed comes to $135.56.
All of the DLC is optional though, and won’t make a difference one way or the other to gameplay; plus skins are pretty much a take it or leave it subject with consumers.
While new maps will be released free-of-charge to all players, there is a Season Pass for Evolve which only comes with three skins exclusive to the package and four extra Hunters when they become available.
None of the content listed in the links above is included in the $24.99 Season Pass.
The Hunters will cost those who do not own a Season Pass $7.49 each.
