The year is 1989. 12 years have passed since the Gogoh Army’s invasion of Earth. Exposure to alien technology during the war enabled Earth’s own technologies to take massive leaps forward. International conflict that was previously rife in the history of mankind fell to an all-time low, and the Earth Federation was established as a...

Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Jul 24 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Bad
Decent robot action, similar to Metal Warriors, Assault Suits Valken / Cybernator, and Front Mission 2. If you like old school shooters like Gradius, and you thought they could use a little bit more giant robots, then this is probably for you. My only complaint is that there doesn't seem to be the able to pause or quit once a game has started. Aside from that, this is a very enjoyable arcade-style romp.
Que surpresa foi esse game! Incrível como o gameplay muda de acordo com a configuração de armas que você escolhe antes de entrar no campo de batalha! Precisamos de mais jogos nesse estilo. Muito divertido!

good game
Sadistic normal difficulty kind of brings the whole experience down for my tastes but it IS a very fun shooter with some great music and a decent combination of weapons to choose from. I couldn't get past level 5 myself but if you're really good at bullet hell type of games then by all means, go for it. But for those who aren't die hard shooter fans, this may prove to be just a bit too much of a challenge.
I love it.
Really good mecha shmup, with a nice selection of weapons and difficulty settings. Quite intense.

Set at a point in time between [b]Vulkaiser[/b] and [b]Gigantic Army[/b] but, to make things confusing, released on Steam after the latter and before the former, this game has a thin plot consisting of the classic hidden super bad organization that somehow manages to seize so much military hardware, they can wage war on the whole world, in an alternate 1989 where an alien invasion the previous decade, of course repelled with a big mecha, led to Earth getting very advanced tech early. There would be a more complex lore but it's tucked into the Japanese website of Astro Port. All that ultimately boils down to a flying mecha with the ability to shift the direction of its main weapon up and down when not shooting, coupled with a secondary weapon and a self-recharging special attack. After deciding the loadout, there's little to do beside shooting down everything that moves. It's pure, simple, classic shmup with zero frills, and does the assignment greatly. The special attacks are very balanced in their strengths and weaknesses - don't sleep on the pile bunker, which has short range but stops even bullets. Artist and musician SAK does the usual excellent job with mecha designs, with some of the most interesting being actually in the early levels as haphazard fusions of contemporary military vehicles and futuristic tech can be seen. The second boss revealing itself as a transforming mecha is also worth mentioning. The intro is "simple" but sets the mood, and before the final mission there is a beautiful sequence. Music is possibly even better, a soundtrack that is at the level of the best shmups of the 16 and 32 bit era. It's a very short game: an average full run lasts 15 minutes. However, just as with any good title of the genre, actually managing to reach the end at higher difficulties is another matter entirely. Besides, it's so fun and tightly paced, a perfect game for when you have half an hour free, and is priced accordingly. Just like a few other Astro Port games, there is a Switch version which would be nice to see on PC too, but leaving the original available because, while it has a remixed soundtrack, the graphics have been made more colorful for the sake of it, resulting in some questionable chromatic choices!
元々はデザエモン2用に作られた「鉄機兵序曲」というSTGで、ソレをパワーアップ、ブラッシュアップした作品。非常に硬派で面白く、リアルロボット系の鉄臭い量産機などが大好きなら気に入ると思います。 STGとしても爽快感が高く、音楽も作品を盛り上げていく硬派なものぞろい。最後までよくできている作品です。
