Halo 3: OSDT has indeed been added to Halo: The Master Chief Collection before the end of May. We've captured a few 1080p/60fps videos of the game that you'll find inside if you're curious to see what this new port looks like. We'll also add some multiplayer footage of the new map Remnant, which is actually the remastered version of the famous Relic. Update: Two Remnant videos added. Update 2: Last video added.
@Moonwalker: they don't sell on the west in any platform either. not in any sales that are meaningfull for the publisher just for the small niche dev. it's just that localizing is a effortless job (1 Hour ago)
@KORNdog: it's a shame though. 360 had a lot of these games but they are all gone now. I guess they don't only not sell on Japan, neither in the West too. (7 Hours ago)
@Moonwalker: unless he takes a few truck loads of cash with him...no. (8 Hours ago)
