"That giant spider wasn’t something new, but something very old. And it was built specifically to keep that data core out of anybody’s hands." - Foster

The Spider 'Mech was a super weapon created by Jerome Blake. It was the first boss encountered in MechAssault 2: Lone Wolf.


The Spider 'Mech was created in secret by Jerome Blake, the founder of ComStar, using technology that Blake himself had invented revolving around the manipulation of plasma. Weary of his own creations and fearing that they would only be used to destroy, Blake ultimately chose to hide his magnum opus, the Five Data Cores, in secluded locations far apart from each other so that they would not be assembled and misused. Blake trusted the knowledge of the existence of the Five Cores to only a select few known as the Covenant, who would be the caretakers and protectors of the cores until mankind was ready for all that they could give.

However Blake anticipated that the personal feelings and beliefs of the Covenant and those who proceeded the original members could influence them towards abandoning their duty to protect the Five Cores and instead attempt to unite them and harness their power to further their own ambitions. Blake therefore created a contingency plan: that he would summon all of his skills to construct a heavily armed and armored automaton infused with the power of the Plasma Data Core, with it's sole purpose being to defend the core at all costs.

Blake constructed the Spider 'Mech in secret and designed it primarily for extreme combat and to operate as long as it could. The Spider 'Mech closely resembled its namesake, although it had only six legs whereas spiders generally have eight. Designed to last indefinitely, Blake built the Spider 'Mech with the intention of having it operate alone without any maintenance or repairs. While it possessed a shielded body that could repel all attacks, the Spider 'Mech’s legs were reinforced with heavy armor that could only be destroyed with high amounts of damage. Blake armed his creation with an arsenal of missiles and a powerful plasma cannon that utilized the Data Core the Spider 'Mech was programmed to protect. Once completed, Blake programmed the Spider 'Mech to destroy anything that came within its proximity with all the weapons it had at its disposal, and to even physically charge at enemies with the intention of protecting the Data Core at all costs.

Once completed, Blake sent the Spider Mech to the planet of Thestria, a world with no strategic value aside from its mineral deposits, vast swaths of secluded, uncharted land and a very small human population that would be unlikely to discover it. There the Spider 'Mech remained hidden for centuries and managed to stay fully operational during that time to the point where it was seemingly unaffected by any form of natural degradation.

All information beyond this point will pertain to the Spider 'Mech from an in-game perspective and provide direct gameplay information including the boss' behavior, weapons and attacks, and guides on how to defeat it.


The Spider Mech appears to have 4 types of weapons.

  • An extremely powerful Plasma PPC. This causes massive damage and is capable of tracking your 'Mech. This fires from the 'mouth' of the Spider Mech.
  • A Plasma Beam which can be fired in what appears to be 160 degrees out from the front of the Spider Mech. The Plasma Beam is it's most powerful asset, as a continuous barrage of plasma can quickly decimate your 'Mech or BattleArmor.
  • What appears to be Crossbow Missiles launch from its 'back'. About 6 to 12 missiles can be fired at once. The more damaged the Spider is, the more missiles it fires. Not truly damaging unless in the BattleArmor.
  • Stomp Attack, the front two legs of the Spider Mech stomp the ground, which causes any 'Mech near the front of the Spider to fall over. Causes light damage.

Attack Pattern[]

The Spider 'Mech is the fastest 'Mech in the game, it cannot be outran as it is very relentless in pursuing its 'prey'. It's general attack pattern is shown below.

Part 1: The Spider 'Mech will charge at you, possibly firing what seems to be Crossbow missiles and then performing its stomp attack.

Part 2a: The Spider 'Mech smashes the ground with its two front legs, if you are too close to where it is pounding the ground, your 'Mech will fall over and the Spider will use either the Plasma Beam or the Plasma PPC.

Part 2b: If you manage to evade falling over, the Spider Mech may fire a Plasma Beam. If the spider mech is not very damaged, it will fire the beam in a line. If the Spider 'Mech is badly damaged, the Beam may move and fire in an area of what appears to cover 160 degrees. The Spider 'Mech will be stationary while firing its plasma weapons, getting behind or even off to the side will keep you unharmed. Or see part three.

Part 3. The Spider 'Mech will leap into the sky and land somewhere away from your 'Mech/Battle Armor and charge at you again, repeating the process until you are dead, or the Spider 'Mech itself is destroyed. Once the Spider has taken enough damage, it will remain in its position, slowly turning, struggling to face your 'Mech. Once in its crosshairs, the Spider will use its Plasma weapons in an attempt to destroy your 'Mech/Battle Armor.

Defeating the Spider 'Mech[]

In order to destroy the Spider' Mech, you must avoid being knocked over by its stomp attack that it does after it charges at you. To avoid falling over, continue moving backwards and sideways (diagonally backwards to the left or right). If done properly the stomp attack will not knock you over. You only have a few seconds to do any damage to the Spider 'Mech after it's done its stomping attack. Aim for the legs, you need to destroy all eight for the shielding on the main body to deactivate. Its attacks become more and more aggressive as you continue to destroy the legs. The Plasma Beam will spread from its mouth and move around, being directly behind the Spider will keep you safe from its devastating beam range. The Spider 'Mech may just charge you and then jump back to the center, not giving you any opportunity to destroy its legs. After all the legs are destroyed, shoot the main body. After a handful of shots, the Spider 'Mech will fall inward and blow up. Stay away from the 'Mech after it collapses, the resulting explosion is the largest 'Mech explosion in the game, and will instantly kill anything.


  • The explosion seen from when the Spider 'Mech dies is the biggest 'Mech detonation in the game. It is bigger then the Uber 'Mech's explosion at the end of Lone Wolf.
  • The Spider 'Mech is the largest enemy vehicle you'll encounter.
  • The default spawn when loading the level has you in a Mad Dog but If you beat the previous level with the Thor or the BattleArmor, you will use said 'Mech against the spider boss.
  • If you complete the previous level in the BattleArmor, you can attach yourself to the supporting VTOL by standing on top of the spider and be carried into a secret area where the VTOL supplies itself and the 'Mech stored for the cut-scene is also located.
