Hover Bombers are one of two different aeroplanes in Metal Fatigue, the other being the Hover Jet. They are created and stored in the Aircraft Hangar. However, unlike the jet, the bomber requires a Research Facility to be built before production may begin.
Bombers have a particularly lethal attack, though they may only target ground units, and are thus particularly vulnerable to opposing jets as they are also slower. However, being an aircraft, they may of course easily traverse the Orbital Layer. If unchecked, bombers can easily massacre enemy units and lay waste to enemy bases, even causing significant damage upon death due to their immense payload.
