2MORO is my online MMORPG- it's a browser game, not zombie intensive although there is one level crawling with them.
However TECUAQUE is going to use the same game engine but revolve around the survivors of a zombie outbreak on a tropical island. The game will feature initial choices of origin for your characters which will create entirely different storylines covering all the major zombie types and subgenres.
