A decent gun action anime. It's no Lycoris Recoil, SAO 2 and SAO: Alternative. But, it's a suffice watch. Although I've never played the game this anime is based on, at least as of typing this, I was able to follow along with the story, which while simple is effective. The only disappointing aspect of this anime, is the animation. Compared to SAO, a lot of times, the characters are just standing still shooting at their enemies. Rarely do they run and gun to make the action more engaging. But otherwise, if you want a military-themed anime or wanted a Call of Duty anime, this'll do just fine.
