Major Nelson informs us that Halo Wars' "Strategic Options" DLC is available now for 800 ($10). The pack includes three new game types and 100 points of Achievements (no maps?).
If the price seems a bit steep for a few game types, we've got that covered too. We've got a post up now to win one of five free codes. Good luck!
