I have to assume this was Konami's answer to games like Gun.Smoke, Commando and Ikari Warriors, but it doesn't do much to stand out. It's fine really, surprisingly more fair than I expected from a Konami arcade release of this vintage, the typical last level quarter-muncher notwithstanding. if ranked, It'd probably fall somewhere in the middle of Konami's arcade output for the time - It's clearly a trend-chaser rather than an innovator, which isn't necessarily a negative but you'd be forgiven for forgetting it exists; Konami sure did.
