In July, Microsoft began its Games for Gold program which allows Xbox Live Gold members to download two select games for free, one on the 1st then another on the 16th of each month. On August 1st, Xbox Live Gold members will receive Crackdown and then Dead Rising 2 and its mini-prequel Dead Rising 2: Case Zero on the 16th until the next month’s games replace them.
Typically offering two games, Microsoft seems to be giving gamers an extra bonus by including Dead Rising 2‘s prequel with the main game. This is the perfect chance for anyone who passed up this game to play the full story. Downloads during Games for Gold are considered yours once you download then, so I’d recommend grabbing them if you don’t own them already.
