Serious Sam 3: Before First Encounter is getting serious on Xbox Live Arcade next week, launching on October 17 for 1200 MSP. Devolver Digital also announced that the "Jewel of the Nile" DLC arrives on the same day, just a day after it debuts on Steam.

The DLC includes three new campaigns along with some new weaponry. It's available with the Deathmatch, Capture the Flag, Lat Team Standing and My Burden multiplayer versus modes for 1200 MSP too.

Devolver Digital revealed the above trailer to commemorate the announcement. It features the Rich Knuckles character from previous BFE commercials holding down his new mobile helpline, and includes an interesting soundbite from a certain CEO.
