Clubs (steel bars, parts on bulidings) can be used to do more damage when hitting other monsters, and can be thrown. Vehicles may be thrown, but do little damage, these include taxis, helicopters, tanks, buses, propane tanks, planes, rocks, debris, ventilation systems, UFOs, gas trucks, and other items. Some may have a special effect, such as exploding and setting a monster on fire or a generator that can be used to shock a monster.
