See Halo's Enemies, Vehicles, And Master Chief All Drawn To Scale
Artist Andrew McGee, who brought us every colossus from Shadow of the Colossus drawn to scale, as well as a similar piece comparing Half-Life 2's assorted monsters, vehicles, and humans, has release a new piece focused on all things Halo.
The sizes aren't quite as perfect as McGee's last pieces, but for good reason. On his blog explaining the piece, McGee writes, "The sizes are slightly more approximate than the last two posters, partly because they vary over the games, but there’s nothing glaringly inaccurate (that I can see, anyway!)." If you want to buy the piece as a large print, you can do so by heading here. McGee is only planning on selling 50 of them, so you better jump on it if you want one.
