Age of Conan: Hyborian Adventures will be publicly playable for the first time GC, developer Funcom announced today. The massively-multiplayer online role-playing game based on the Conan the Barbarian universe features a siege warfare system that will be shown to media for the first time at GCDC this week. Fans attending the conference will also be able to hack at each other one-on-one on the show floor, Funcom said.
