What can I say -- it's a mobile game, first and foremost.
The premise is decent. Full voice acting, at least some unique-looking assets, and pushing its simple story from the beginning to the end are all positive points of that game. There are varied weapons, varied enemies, and relatively varied layouts aboard the presented ship. The gameplay is dead simple -- here, you have a ship and some zombies, shoot them around. That basic concept is executed well enough -- it's absolutely playable as a shooter game, and it's not the worst.
As for the gameplay nitpicks, it doesn't all work together that well, and the over-linear level design highlights more gameplay problems. Eg -- many corridors are so tight that you cannot move past enemies, but at the same time often enough there are no alternative paths so if you misused your ult, you're just stomped to death. This is pronounced even more visible by the grenade-throwing enemy, which could be fun if you, well, could move even a meter to side to avoid their grenades, but in way too many corridors there's just no space for that, so you can only watch the grenade fly towards you and one shot you.
Sprinting cooldown being two years long, coupled with rather slow basic movement speeds, makes navigation a slog at times, but this is largely compensated by the levels being equally tight.
And the last, unfortunately negative matter -- the game hasn't escaped the mobile game mentality. Almost all upgrades are purchasable from shop for in-game currency (which, I presume, used to be obtainable via microtranscations), except the ratio of which you can obtain it is abysmal, so my two-hours-long playthrough ended with just one purchased weapon, which wasn't even halfway upgraded. You also pay up to 1/5th of per-level reward for each of your deaths, which -- with random deaths caused by near-unavoidable grenades -- slows the progress just too much. Expecting someone to replay the game like twenty times just to explore all the available weapons, while at the same time not providing any alternative paths or better-than-average gameplay is too much.
Overally it's very 50-50 for me. It's a technically-playable, crusty game, ultimately made to catch some Dead Space spotlight on mobiles. At the same time, I don't think I'd go out of my way to spend one dollar and 2 hours of my life on it again.
