If you're still living it up in Halo 5: Guardians multiplayer (and you probably are because there are some sweet modes) you might be interested in next week's upcoming Infinity's Armory content.
When the update drops, Halo 5: Guardians players can enjoy two new maps, a new Legendary weapon, new REqs, skins, three armor sets, and a whole lot more.
There's a new Arena map called Riptide, as well as a Warzone Assault map called Urban. If you're feeling like going enemy-hunting, you can suit up with the Halo 2 Battle Rifle, unlocked in Forge as well if you want to recreate Halo 2 maps or something crazy like that.
The new content will download and install automatically for everyone who owns the game, so you don't have to do any work to claim all the new stuff. Fancy hopping online and testing it all out? Now's a great time to.
