after playing Neurolink it for 2 days straight
i found that STUDENT having the worst special ability , it keep making me stuck on rubble or make you slip as this can be fatal at boss fight.
PHD is the best volunteer in my experience as he can attack very far and make your ability have less cooldown while having the best active passive at start force choke , force choke with spike with no other knockback active passive is the best on PHD as you can kill boss in just 3 second stun locking them.
now DISGRACED CEO is the buggiest volunteer model i found , his suitcase keep getting stuck at rubble, enemy or wall, with his passive more enemy it's really make it more pain in the ass to dodge enemy attack as it's better just stand there menacingly , if there's someone want to win with this do not ever pick LEVITATE it will make you stuck most of the time.
overall the game is really good
