Each part in Evolve is vital; however the Trapper has higher need in Hunt. Without a Trapper, or a great one, the beast will escape and get to stage 3. Maggie makes discovering the beast simple with her pet trap jaw, Daisy.
Back in 2016, Turtle Rock announced that support for its 4v1 monster-hunting shooter Evolve would end but fans wouldn't let it die.
From NME: "Evolve: Stage 2 had its multiplayer servers shut down back in 2018, but today players are once again able to matchmake and join peer-to-peer multiplayer games.
Several months ago, peer-to-peer functionality was lost for Evolve Legacy, which was the only way fans of the series could play with friends. Upon a multitude of players reaching out to publisher 2K, the issue was eventually fixed earlier in July. It seems 2K have gone a step further now, and reinstated peer-to-peer and matchmaking functionality for Evolve: Stage 2 after four years."
