The magnificent Humble Deep Silver Bundle has become even more ridiculous thanks to three more games being added as 'beat the average' bonuses. Metro 2033, Risen and the recently-released Sacred Citadel have joined the roster in Steam key form, and have been automatically added to your key page if you've already beaten the average price.
So here's the roster as it stands: Saints Row: The Third Complete, Saints Row 2, Risen, Risen 2 Gold Edition, Sacred 2, Metro 2033, Sacred, Dead Rising GOTY, Sacred Citadel and soundtracks. For £3.30. Just do it.
