Easily one of my favourite PvP games because of the species dynamics and the lobby options. Used to play it at LAN parties now and then, up to maybe 8 players. Once you had enough players it was great to have 1 Predator vs 2-3 aliens and the rest humans. Species were selected at random so sometimes you’d get a derpy predator or a one hunter killing machine. It always lead to interesting games that sort of naturally lead inadvertently to roleplay scenarios like the humans keeping an eye on vents and banding together.
Oh and alien life cycle was always on for more challenge to the alien players. Trying to find a facehugger victim in and trying not to get blasted straight out of the chest as a chestburster to become the ultimate killing machine.
