Xbox Portugal has posted scans from an upcoming Halo 3 feature to be published in Swedish mag Level. Some serious translation work is needed before the full story comes into focus, but we have gathered that the images are from an alpha build of Halo 3, suggesting that many of the details won't reflect the final version. Check out the one-manned mini-Warthog Mongoose!
