Security Robots are way better armed than the Maintenance Robots, with a built-in laser cannon. They are designed to defend high security areas.

Security Bots first appear on the Operations and Recreation Decks. After destroying one, you should search its chassis for salvageable equipment. You can occasionally find Prisms or containers of Iridium.


  • As with all mechanical foes, the Dual-Circuit EMP Rifle or EMP Grenades are the weapons of choice. An attack with Armor-Piercing Bullets is just as good.
  • A bit worse (but still effective) are the Energy weapons.
  • If you have none of the above, Disruption Grenades (or Fragmentation ones, assuming the Grenade Launcher is upgraded) will suffice thanks to the massive amount of Standard damage they deal. Also, since Bots move slowly you can try lacing their path with several Proximity Grenades, which they will blindly blunder into.
  • Melee weapon users should approach all the big Bots as close as possible and press on when attacking, preferably from their right side, where they are harmless (until they turn). Either circle-strafing or rushing while attacking (assuming they can't aim at the player) is a good strategy. Of course, their explosions will hurt the player in a small way, since it deals some Standard damage.
  • A great strategy against all big Bots in general is to lead them around the corner clockwise. This way they can be attacked, but their weapon arm will be obstructed so they won't shoot.
    • The opposite is the worst cast scenario: when they follow the player counterclockwise, only their weapon will lean out around the corner. They will be able to attack the player, at the same time being very hard to hit themselves.
  • Their laser is way more damaging than the Maintenance Robot's spark welder, and considerably more accurate. Its projectile is also a lot faster. However, the attack is still Energy-based, so one can use Energy Reflection Psi Power to halve its damage.
  • Large Robots will explode upon destruction similarly to a Protocol Droid. When low on ammo, first use a melee weapon to wear them down, then finish them off with distance shots to avoid being caught in the explosion.
  • The explosions of these Robots deal distance-dependent splash damage. This means the further we are from it, the less damage we'll receive. The maximum damage of 8 is in the very center of the explosion and can only be received if the Bot moves towards the player, and the player approaches it from its side, moving fast enough.
  • The Security Robots are vulnerable to the Stasis Field Generator and the Electron Suppression Psi Power.
