As you progress through the Kaida facility, you will inevitably face boss enemies, very tough foes who require a level of strategy to defeat. They must be defeated in order to progress.

A boss will always appear after completing a set amount of areas in each floor.

Boss Variants[edit | edit source]

Bosses can come in a few variants, affecting their performance and healthbar.

  • Shielded
  • Regenerating
  • Reactive Plating
  • Heavy Loaded

First Bossfight[edit | edit source]

Experiment 57[edit | edit source]


Experiment 57 is a large quadruped robot that perpetually moves in your direction. Its attacks include:

  • Firing mortar shells in on your location.
  • Firing laser volleys in cardinal directions (up, down, left, right).
  • Firing homing missiles.
  • Firing homing bolts?
  • Spawning gun drones. The drones sometimes outlive the boss, and do not stop firing until killed.

On the ground are scattered hazards that impede movement, such as barbed wire and spike traps. There are a few concrete blocks that are placed in regular formations on the left and right sides of the arena.


Experiment 57 is manageable as long as the player never stops moving and keeps at medium range. The multiple hazards on the ground encourage the player to never sit too long in one area, or else they expose themselves to damage from the spikes or slowdown from the wire. When battling at extended range, Experiment 57's only real threat lies in its mortar, which is dodged easily with dashing. The missiles can be sidestepped if the player allows the to get close enough: when they are sufficiently near, it is possible to sidestep in a driection perpendicular to where they come from.


  • Upon death, the powerups spawned by the boss kill may appear inside a lingering Psy Field. Retrieving them requires the player to wait until it disappears, or to dash in and quickly step out.
  • Bosses always drop an upgrade kit. While it may be tempting to use it on your current weapon, it can be worthwhile to check if the case dropped by the boss is a weapon. It might be of better use there!
  • Two ammo crates spawn with every boss. Don't forget to top off your weapons!

Hack the Server[edit | edit source]


Hack the Server is a defense boss fight in which you must defend yourself while hacking a Kaida server. During the process, waves of enemies will spawn around the arena and try to disrupt your progress. When the server is fully hacked, it explodes and enemies stop appearing. Enemies spawned include:

  • Breach Cetas
  • SG Rivals
  • B Defenders
  • Workerbots
  • Enforcers
  • OM6 Overseers
  • SPDR Explo
  • Hovertank 808

The server lies in the center of the arena. To hack it, the player must remain close, with hacking speed being proportionnal to distance: when far enough,it reverses at a slow pace. After a set time has passed, the 808 Hovertank appears.


Hacking the server is a battle in which it is useful to stay aware of threats coming from all directions. Since it is difficult to see the spawning locations of enemies when huddled in the center, patrolling away from the server can become a useful compromise between hacking speed and area denial. In times of need, it can also serve as cover. Quickly circling around it is an easy way to breack engagement and wait for shields to recharge.

Most enemies spawned here are relatively easy to dispatch and require no particular mention. The Hovertank is no different: it is slow and its dumbfire missiles pose little threat when sidestepping and dashing through.


  • The server will start beeping before exploding, so don't stay close! As a last ditch effort, this can be used as a signal to lure in and blow up remaining intruders.
  • The powerups will always spawn in the remains of the server.
  • Anecdotal evidence suggests the server bossfight only occurs when being dispatched to the KAIDA Training Floors.
