DeadFrontier, a browser based MMO, similar to Runescape in the fact it's 3D and only requires Flash. BlueDevil is my clan leader for the passed 7 years, except I have been away for the last 3. It's a zombie survivor MMO where you travel by map grids where you fight whole city blocks infested with zombies and sometimes against other players. There are 4 Outpost Bases where you can respawn at and trade Loot with players on a player-based economy and group up with individuals (no platoon system, just a Follow Instance system and Clan system) to hunt Bosses or Daily Event Missions and endless waves of zombies. There's an Old School Mode in the first outpost (I think the portal to it migrated to 3rd Outpost) to play in the classic version in 2D.

It's a lot of fun, especially as a new player, before you come to realize the economy is based around the newest gear, while the prior is nearly discarded; some costing as much as $50 IRL money dropping to $5 6 months later. As long as you play smart, choose the right classes and raise the right skill points (1 melee, 1 silent, 1 for dps), you can do well other wise many will recommend rerolling because of the restat cost and time requirement.
