Robosaru is the centrepiece of all maps in OBEY. Bunnies in control of Robosaru earn $20 every 2 seconds.
The Bunny in control of Robosaru has five direct methods of eliminating Bunnies they deem to be disOBEYing.
The primary cannon has infinite ammo and fires extremely rapidly. However, it is also terribly inaccurate, and kicks up a lot of billowing smoke. This not only makes it very difficult for the Bunny in Robosaru to determine whether or not they landed a hit, it also can provide a means of hiding for Bunnies who were not involved in the original barrage. The cannon cannot deal damage to Bunnies behind solid terrain, and due to a blind spot it is unable to hit bunnies who have made it inside of the Sentry ring.
The flamethrower consumes Fuel, which must first be deposited into the Feed Box. It is useful for eliminating approaching bunnies as the resulting fire provides terrain that is dangerous, opposed to the safe, view-blocking clouds that the Primary Cannon causes. The flamethrower is positioned far lower than the Cannon, and thus can hit Bunnies who are very close to the door. However, the flames do not damage Bunnies who are hiding in water, and care must be taken using the flamethrower around the Feed Box as Bunnies killed with flames are turned into charred Corpses.
The Missile Racks consume Missiles, which must first be deposited into the Feed Box. Missiles travel very quickly and have a large radius of damage, so they are useful for top priority Bunny eliminations. Missiles rarely leave the intended target alive, and the blast radius can be used to hit Bunnies behind cover. Missiles do leave billowing clouds and traces of fire, so care must be taken not to use them excessively near the Feed Box or other high-trafficked areas, for risk of killing OBEYing bunnies or leaving charred corpses.
Sentries are small spires which are located in a circle around Robosaru. Activating them enables them for 25 seconds and consumes batteries, which must first be deposited into the Feed Box. While sentries are active, they will automatically fry any Bunny who moves too closely, or who happens to be already too close. Bunnies wearing a collar are immune to the Sentries' shocks. Sentries are placed close enough and have a large enough radius to prevent uncollared Bunnies travelling between them, unless a Bunny manages blocks the line of sight to the sentry by using stacked items.
The Bunny controlling Robosaru possesses the ability to manually detonate any Collar or placed Mine that is on the map. If a Bunny is wearing or holding the Collar being detonated, they will be killed.
Entering the door at the base of Robosaru subverts the player inside, placing the new player in control of Robosaru. The other player is then killed. The subverting player earns $300 immediately, by default. The setting can be changed in serverSettings.ini under enterRoboBonus.
After entering the robot, all other players are given Collars and an automated message from the subverting player.
The Sentries at Robosaru's base are then activated for 25 seconds.
The original working title of OBEY was 'Robosaru'. Robosaru means 'robomonkey' in Japanese as the robot is a take on the Japanese giant robot/monster theme. In English, the name is intended to also be interpreted as 'Robosaur'
In this older version of the game, Robosaru had a different model which took inspiration from Mechagodzilla.
