High Street retailer GAME is offering Titanfall beta keys as a pre-order incentive. The offer applies to those who've already pre-ordered, or who pre-order from now on (although it should be noted that there are limited quantities available).
The beta promotion hasn't been officially announced by the retailer as of yet, but VideoGamesUncovered did have the following screenshot by way of proof that it's real (see below).
If you don't fancy taking a trip to GAME and have some money burning a hole in your pocket, then you'll be delighted to hear that some people are trying to extort huge sums of money out of desperate parties in exchange for Titanfall beta access. As noted by MCV, beta codes are being sold on eBay, although the linked listing had to settle for ‘only' £100, considerably less than the £35,000 they were originally asking for.
