The Gas Barge is a form of aerial transportation used by the Locust Horde in Gears of War 3. It is a metal carriage capable of supporting several Locust troops that is carried by a large, unnamed creature. This creature appears as a bloated amorphous mass with a gaping mouth filled with jagged fangs. The creature's body is filled with a volatile, lighter-than-air gas that allows it to stay aloft. The Locust control the Gas Barge's course using a crude navigational system consisting of sharp spikes that are poked into the Barge creature's sides, urging it to alter course.
