Surprise! 10G
Get a Double while emerging as a Corpser (Public/Ranked)

---

Gametype: Overrun
Type: Public or Ranked
Map: Any
Requirements: Double kill with Corpser as you emerge from ground

You will need to play in the Overrun mode. As the Locusts, you must earn enough points to become a Corpser. A Corpser costs a total of 5000 points. You need to dig underground and try to emerge underneath two enemies. This should result in instant kills. If you kill two people at once like this, you will get the achievement. It's best to boost this achievement with 2 other players who should choose the human side. Scouts are the weakest of the classes, so the two people that will die should be scouts. Have them stand in a corner and emerge from the ground from below to kill them.
