Okay, let’s get this out of the way first. Should you buy the MG Deep Striker? If you have to ask then no, this kit is not for you.
This kit is purely for fans of the design/Gundam Sentinel. It has zero effective articulation. No gimmicks (the pointless shoulder expansion doesn't count). Its size means most will never see the inside of a display cabinet. To top it off, it’s more expensive than many Perfect Grade kits. Why Bandai expected anyone to buy this kit is beyond me. Yes, I have one because I’m a Gunpla-holic, and a fan of the design, but I’m an outlier. When you think about all the kits that should’ve gotten a proper MG release before the Deep Striker, this decision is downright absurd.
