Immediately after the title hit Steam yesterday, many users were reporting serious issues with the CryENGINE 2-powered PC shooter. Unacceptable sound quality, terrible framerates, deleted saves and a bug that entirely eliminated the HUD were among the various complaints.

"It's not a game," wrote one angry Steam user, not knowing how close he was to the truth. "It's just a joke." Now it appears that those bugs can be attributed to one massive rookie mistake.

"We are fully aware of the problems that occurred with the initial release of M.O.B.," wrote Paleo Entertainment on their official forums. "Unfortunately, the incorrect version went up on Steam. The Alpha version was released initially, this has been corrected."

Paleo adds: "Please log in/log out of Steam to receive the correct version of M.O.B. We will be patching this game periodically to correct any issues that arise, as well as new and exciting features and multiplayer modes!"

While certainly amusing as blunders go, we'll leave it to the frustrated customers to determine whether the joke was appreciated.

Thanks to madcastro for the heads up.
