This has been a big issue for a lot of folk out there but Rebellion recently came out and issued a statement regarding dedicated servers for AvP:
“Despite rumours, Rebellion has always been planning to support dedicated servers for AvP PC and we can now officially confirm that this is the case. Rebellion has always appreciated fan support.”
This comes as a great relief for a lot of our gamers out there. You can check out the entire article here. Thanks to Doomsday for the headsup, as well as jaberwocky36 on the forum.
