Before racking up any more play time on Halo 4's outstanding multiplayer, be sure to sign up for the Xbox LIVE Rewards. That's because the giant reward program is offering a new promotion that gives you free Microsoft Points for the amount of time you spend playing Halo 4's multiplayer.
The Halo 4 Combat Tour offers three different tiers of rewards depending on the amount of time played. You'll get 100 Microsoft Points for 35+ hours played, 300 MP for 70+ hours played, and a whopping 600 MP for 140+ hours played. If you can make it to the top tier than I salute you.
Additionally, the Combat Tour is offering a refund program for the amount of Microsoft Points you spend on Halo content through the Xbox LIVE Marketplace. If you spend 1500 Microsoft Points you'll get 100 back; for 3000 spent you'll get 200 back.
In theory, you could get a total of 800 free Microsoft Points just from this Halo 4 Combat Tour. So stop reading and start playing! Head over to the Xbox Rewards page for more details.
