The second Gears of War: Judgment map pack, Call to Arms, will be released to VIP Season Pass Holders next week, bringing with it three new maps along with a new multiplayer mode called Master at Arms.
While those who’ve purchased the VIP Season Pass will get access to the pack from April 23, everyone else will be able to purchase it from April 30 for 1,000 MS Points.
Included alongside the maps and mode are six armour and gun skins to further customise your characters and weapons, as well as 10 new achievements set to provide 250 Gamerscore.
The maps, set against the Locust invasion of Halvo Bay, are titled Terminal, Blood Drive and Boneyard. While Terminal is centred around a claustrophobic train station, the Blood Drive map will feature a hospital that’s turned into a battlefront, while the Boneyard map offers a chance to explore a makeshift graveyard for those who fell during the assault.
