In Sandtrap, the Eggs fire orange beams into the sand whenever a player tries to exit the map; these beams activate Brute Landmines that are buried along the level's perimeter. The beams themselves are harmless, unlike the beams on Sandbox. In both cases, the Eggs' kills are attributed to The Guardians. To get a closer look at the Eggs in Sandtrap, you'll need to use Pan Cam to exit the map in Theater and fly to any of the towers. The eggs will be near the top-right of the towers.
