METAL BUILD AQM/E-X02 Sword Striker [ Alternative Strike ver. ], Premium Bandai

AQM/E-X02 Sword Striker is a pack developed for close-range melee combat, equipped with a large "Schwert Gewehr" anti-ship sword, a "Panzer Eisen" rocket anchor and a "Midas Messer" beam boomerang. The backpack consists of the Schwert Gewehr, an auxiliary battery, a close combat support information control system, and a thermal accumulator. 

The Midas Messer is shoulder mounted, while the Panzer Eisen is arm mounted and can be used as a small shield. It is worth noting that the Sword Striker on the Archangel is a prototype model, as such the Schwert Gewehr's hilt laser gun is not functionable and is replaced by a beam blade emitter. 

This pack was seldom used by Kira Yamato or Mu La Flaga, usually relegating it to Archangel's Skygrasper No. 2 (piloted by Cagalli Yula Athha or Tolle Koenig). The Sword Striker can also be used underwater due to the design of its weapons, and has the lowest energy consumption, giving it the highest combat endurance.

The Phantom Pain's Report photonovel revealed a new Another Trial version of the Sword Striker used by the Strike E. The Another Trial Sword Striker eliminates the additional shoulder armor, mounting the Midas Messer on a modified Panzer Eisen and doubling their number. It also changes some of Strike E's VPS armor to blue.

The final equipment of the Striker Pack System from the earlier half of the series is released !

Its main weapon Schwert Gewehr can switch between short and long blade modes with its blade extension gimmick to match with the pose.

The Mydas Messer on the shoulder can easily recreate the posture of grabbing its hilt with its original mechanism, and the Panzer Eisen on the left arm can recreate the state when the claw is launched.

Just as Launcher Strike, it includes stand parts for the suspension of Aile and Launcher Strikers, massively increasing the display capability of Strike Gundam.

The pegs and connectors of the expansion pack also can be installed on the choice Strike version of the Gundam Astray Metal Build figure series, giving some new perspective to the Gundam Seed or Gundam Seed Destiny and Astray series units.

It also includes joint arms for attaching the Striker Pack to METAL BUILD Gundam Astray Red Frame Kai (Alternative Strike ver.) and METAL BUILD Gundam Astray Blue Frame Second Revise (both sold separately), by which you could make the display with two swords equipped and enjoy many more variations in MSV project Alternative Strike.
