Ages ago, Evolve: Stage 2 had this patch:
and it says this about the AI:
Update to Hunter AI
The Legacy Hunters have been updated with a new AI blueprint, so be sure to check out the new AI on Val, Griffin, Hank and Markov!
This basically made the above bots lead and split into two groups (like the video below) of random mixture; e.g. Assault and Support, Medic and Trapper, or one switched and such (it however, unfortunately broke the AIs picking up buffs from elite wildlife).
However, those ain’t the only four AIs that had this update, others did too:
Note: Today, I tested all the AI characters to see who leads and I found out even more lead.
So in alphabetical order:
Healer: Lazarus, Slim, Val
Support: Battle Cabot, Bucket, Hank
Trapper: Abe, Crow, Griffin, Jack
Assault: Hyde, Lennox, Markov, Parnell and Renegade Abe.
Any other hunter AIs I didn’t mention use the default follow AI (they will pick up buffs though, compared to the above).
Lastly, for the bots to lead, all slots must be filled with the leading bots e.g. if you are Markov and you have EMET, Bucket and Jack, they won’t lead, due to EMET being a default follow AI, so they’ll all switch to follow AI (doesn’t mean they’ll pick up buffs though, only EMET will, since his AI mode wasn’t changed).
So yeah, if you still play Stage 2 offline and want the bots to lead the way (split up into two), just play any hunter and pick the above hunters.
