The Berserker was designed as a massive close range brawling 'Mech. Because it is designed to engage an enemy at close range, the 'Mech needs to be able to close with its target to bring its incredibly destructive power to bear on an enemy. To do this, the Berserker is propelled to a top speed of 86.4 km/h by using a Pitban 400 XL engine and a MASC system. The Berserker also uses sixteen double heat sinks to handle the heavy heat load produced by its arsenal of high-heat energy weapons. The Berserker was armored with eighteen and a half tons and shielded by a Guardian ECM Suite, protecting against electronic warfare efforts; it is equipped with a MainFire Point Defense anti-missile system to provide point defense against missile attacks.

Weapons and Equipment[edit]

The Berserker is armed with a Defiance 1001 ER PPC, which it uses to engage the enemy at long ranges as it closes with its target. As the range gap closes, the 'Mech is able to bring its two Sutel Precision Line Large Pulse Lasers to bear on its target, more than doubling the amount of damage the Berserker can inflict on a target. Finally, as it closes to arm's reach, the Berserker can use its Hatchet to deadly effect. A Zippo Flamer is also carried in the head, more for an intimidation effect than any practical combat use, though it is effective against unarmored infantry.


  • BRZ-B3 
    The B3 variant is a modification of the Berserker that changes the 'Mech from a powerful brawler to a well-armed fire support 'Mech. The twin Large Pulse Lasers have been replaced with a pair of Coventry StarFire LRM-10 launchers which allow the 'Mech to sit at long ranges and bombard the enemy. If a 'Mech closes to short range, the Berserker can act as its own bodyguard by using its Hatchet.[1] BV (1.0) = 1,659[5][6], BV (2.0) = 2,020[7]
  • BRZ-D4 
    This Berserker uses an Endo-Composite chassis. It uses a Clan-spec extralight engine to move at 64 km/h. A Compact Gyro that has been Armored makes room for an Angel ECM Suite in the center torso. The 'Mech retains the Hatchet, Flamer, Jump Jets, and Triple Strength Myomer of other Berserkers, but the weaponry has been replaced with a Bombast Laser and four Clan-spec ER Medium Lasers. The largest difference is in the protection: this model has been equipped with Impact-Resistant Armor. BV (2.0) = 2,659[9]
