343 Industries has been gracious enough to share with us the eight Xbox 360 Achievements that will be available when Halo 4's Crimson Map Pack is released.
The Crimson Map Pack is the first of three Map Packs planned for the War Games Map Pass. It includes three new multiplayer maps — Wreckage, Harvest and Shatter (details and trailer here) — along with a new Crimson DLC Mathchmaking playlist. More importantly, for you Achievement hunters out there, the Crimson Map Pack offers eight new Achievements worth a total of 250 Gamerscore.
343 Industries has revealed what you'll need to do to earn each Achievement and how much each is worth. It looks like a lot of them have to deal with vehicles.
