Players split up into two teams, with each player taking on the role of prominent characters fromandgames. Each team then tries to destroy the other team's base while defending their own. Over time these characters can level up and develop new abilities.This simple gameplay formula, first seen in thecustom map, has inspired the mega-hitas well as prominent competitorsand. Breaking into this genre won't be easy for Blizzard. A beta seems like a good way to try and win over fans of other Blizzard games or the competing MOBA games.In the case of's expansion, a beta could be a way to bring players back. Player numbers have certainly dwindled since the's launch last spring, with players either being disappointed by the sequel or simply running out of things to do. Blizzard could lure both groups into buying the expansion by doing another small preview like they did with the base game . The beta might also encourage people to start playing regular oldagain, which would be a boon to Blizzard if it makes the real-money auction house more active.Pardo didn't provide dates for theorexpansion betas. That's not surprising, as the company hasn't announced release windows for the full products either.
