Previously Mercenaries co-op play was only possible offline through system link for the Xbox 360 but now gamers can play it over Xbox Live too.
There's no word if a patch has been submitted for the PS3 version yet. The high scoring Mercenaries mode is unlocked once the Resident Evil 5 campaign is completed.
"A title update is already available for RE5 which adds online co-op play for Mercenaries Mode on Xbox 360," reports .
This update has arrived before the game has officially released, which is this week on March 13th for Xbox 360 and PS3. Planning on some online co-op high-score attack action? Capcom hopes you are.
