This is the EG Strike Gundam I already liked, wearing a Gundam Breaker neon jacket and carrying four floating gunbarrels I didn't know I wanted.
I built the base suit in under an hour and it moved the same way the standard EG (2020) Strike does, which is to say confidently, but the Gunbarrel Striker pack is what earns this its own review. It's all new tooling, not a reuse of old HG SEED runners, and it shows in how cleanly the pack and its four remote pods snap together and peg onto the backpack.
Best for: Strike Gundam completionists and Gundam Breaker 4 players who want the neon collector's-edition suit on a shelf, not just in-game
What it is
Underneath the color scheme this is the same EG Strike Gundam skeleton Bandai launched in 2020, which means double-jointed knees, ball-and-socket shoulders and hips, and an elbow that folds past 110 degrees without any of the frustration EG's earlier years were known for. What makes this specific release worth tracking down is the Gunbarrel Striker on its back. It's a new mold, not a repaint of the old HG option parts, and it holds four small gunbarrel pods that clip off the wings and pose on their own display stalks like they're firing independently. Building it took me under an hour and the gate placement was clean enough that I barely needed to sand anything visible.
The catch
This was a Gundam Breaker 4 Collector's Edition exclusive, so it never had a normal retail life. If you want one now you're buying secondhand or paying import markup, and the price floor sits well above what a standard EG usually costs. The neon magenta and cyan colorway leans hard into game aesthetics rather than the show-accurate Strike look, so it won't fit next to a SEED-accurate shelf. A few of the extra Gundam Breaker markings are decals rather than molded color, and the gunbarrels need their own display stands if you want the floating-weapon pose, which aren't included.
Who it's for
Grab this if you already like the EG Strike Gundam's handling and want a louder, gadget-heavy version with a genuinely new accessory pack instead of a straight recolor. It's also the obvious pickup for anyone who played Gundam Breaker 4 and wants their in-game loadout on a shelf. Skip it if you want a show-accurate SEED Strike, since the neon scheme won't match, or if the secondary-market price for a bundle-exclusive kit doesn't sit right with you. A standard EG Strike plus the separate Option Parts Set Gunbarrel Striker gets you close to the same articulation for less money and hassle.
The build story
What the build is actually like, and the engineering worth knowing about.
The base body goes together the same way the 2020 EG Strike does: short, satisfying steps, forgiving gate placement, and part fit tight enough that I didn't need cement anywhere. The Gunbarrel Striker pack takes a little longer since it's new geometry, but the pods clip on and off the wing mounts with a positive click rather than a loose friction fit, which matters once you're swapping them between the backpack and their stands.
Articulation carries over everything that made the plain EG Strike good, ball-and-socket shoulders and hips, a double-jointed neck, tilting ankles, so the suit holds wide poses without the elbows or knees sagging. The neon color separation is genuinely strong for the price point, with the eyes and most panel accents molded rather than stickered. The kit is also backward compatible, meaning the shield and beam rifle from the standard EG Strike, and the Aile or Launcher/Sword Striker packs from the 1/144 Option Parts Set, all mount straight onto this frame.
Lore & trivia
- 01The Gunbarrel Strike was originally conceived within the Gundam SEED story as a planned personal unit for ace pilot Mu La Flaga, built around wired gunbarrels that only pilots with exceptional spatial awareness could control effectively.
- 02This kit's Gunbarrel Striker pack uses entirely new tooling rather than reusing runners from the older HG SEED Gunbarrel Dagger kit, giving it a cleaner fit than the option-parts version.
- 03It released August 29, 2024 exclusively inside the Gundam Breaker 4 Collector's Edition, molded in a neon color scheme meant to echo the game's stylized aesthetic rather than the anime-accurate Strike Gundam palette.
- 04The in-game Gundam Breaker 4 version this kit represents swaps to wireless gunbarrels and can mount weapons borrowed from the GAT-X103 Buster Gundam, details reflected in the kit's extra hardpoints and sub-arm connectors.
