Gameplay Monthly has tossed up a somewhat positive review of NCsoft's Dungeon Runners, giving the massively multiplayer action RPG an overall score of "B."
If you've played Diablo then you should know what a dungeon crawler is. This is more or less a spoof off of Diablo, combined with some aspects of Guild Wars and World of Warcraft. If you haven't played either of these games, here's the basic idea: Go into a dungeon, kill monsters, gain levels, get phat loot. Rinse. Repeat. You have the option of a PvP based game with Arena combat or a PvE based game with dungeon crawling. It's a simple formula, but something doesn't need to be complicated in order to be fun and addicting.
