Cons
Con Pretty much dead

Con Bad netcode
They made an HD remake of the original Painkiller, and that's regrettably the only thing they improved on. This game was fantastic on LAN and tournaments, but horrible online if you're pushing above 40 ping. Painkiller's bad netcode primarily contributes into the game's unpopularity as well.
