Also unlike most fighting games, players are allowed to roam freely within the city area, which allows climbing of jumping from buildings and cliffs. Monsters can use the environment to deal out damage to their foes by making weapons of various objects found within the city, such as vehicles and rubble as projectiles, steel girders and stone columns as clubs and radio antennae as a spear to impale others, temporarily stunning them. There are also some environment pick-ups, which can increase health or stamina, appearing as green or blue orbs and floating radioactive signs. Buildings can be destroyed if a monster directly attacks or is thrown into it. In some cities, taller buildings can topple over sideways that can crush other monsters, killing them instantly.
