For only 800 Microsoft Points (or $9.99), the new Khyber Strike DLC will get you three new multiplayer maps and a new gametype.
The new maps are as follows:
- Switchback: a close-quarters map full of cramped alleyways narrow streets.
- Palace: a massive building that was once a museum.
- Transit: an abandoned metro station in Moscow.
- The new gametype is known as Takeover, and will work similarly to the team deathmatch mode from the COD franchise.
