Dungeon Fighter Online's Act VIII: Under Siege update. Every Thursday and Saturday from 5:00 p.m. to 6:00 p.m. PDT, Dungeon Fighter Online players will need to team up to repel the hordes bent on wreaking havoc and destroying all in their path.
DFO heroes will be handsomely rewarded for successfully driving off the beasties, while failure in the city defense initiative means that NPCs will deny trade and repair opportunities for a time. Additionally, Act VIII brings the ability for max-level players to choose professions (which in turn grants access to skills such as alchemy, enchanting, disassembly, and animation).
Players will also be able to increase reputation and status via a new system that involves gifting NPCs with various items to build friendship and trust. Check out the DFO website for further details.
