A player deploys the "bubble shield" equipment using the X button and an egglike device appears, quite a bit larger than the object seen in the "Starry Sky" CGTV ad from 2006.

Also unlike that device, which the Chief spiked solidly into the sand and remained stationary even after a Wraith blast, this semispherical device rolls down slopes, which could be a help or hindrance to players deploying it, depending on the situation.

It is presumed that gunfire and explosions do not penetrate the bubble shield in either direction. It is not known if explosions from inside the shield can affect the device's position and motion. It is presumed that players and vehicles can pass through the shield.

After it is deployed, it slips through the player's legs.
