Those who Kickstarted Oculus Rift were originally supposed to get a copy of Doom 3: BFG included with their order, but that is no longer the case. "Unfortunately, we've been informed that [the game] will not support the Rift development kit by the time we begin shipping," wrote the Oculus team. Specific reasons for the delay were not given.
Given this spot of disappointing news, replacements are being offered to those affected. You can either get a $20 Steam Wallet credit or a $25 Oculus Store credit. There's also the option for a full refund of your Kickstarter pledge. If no option is chosen via the Oculus Order Manager by April 5, the replacement will default to store credit. At least there's still Hawken.
