What Steam players say
Recent verbatim reviews from Steam — separate from playze.io community reviews below.
The game focuses entirely on gameplay and comes without any real baggage in terms of story or justification for blasting through waves of enemies. Your goal is to move through a series of stages and destroy tanks, jets, and other hostile units before they destroy you or your headquarters. The path to the final stage is mostly linear, though there are a few side missions where you must carefully maneuver your ship through minefields, collect supply crates, or protect a supply ship. In total, there are 45 stages. The mechanics are based on the twin stick shooter formula, which means you move with one control stick while firing with the other. You can also play with a keyboard and mouse, which may even be the recommended option due to the increased precision it provides. In addition to your main gun, you have access to special weapons, bombs, and missiles. Unlike the primary weapon, which has unlimited ammunition and no restrictions, these secondary weapons require a cooldown period before they can be used again. Beyond the main objective of destroying all enemies, each mission includes two bonus objectives that are always the same. These include completing the mission within a set …1 found this helpful
Progression system makes you to grind. Enemies fly out of your screen half of the time wth
This game plays nicely, and there are certain aspects of it that I like: visuals, effects, controls (even though it claims to be a game designed for controllers, it can be played via mouse and keyboard well enough). There are some areas the devs should work on: - General monotony of missions and enemies, staleness of tactics (fly fast, hit and run); - Confusing UI (haven't figured how to buy or equip secondary weapons, missiles or bombs); - Chaotic movement of aerial enemies (fly off above the top of the screen).
