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.

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.

積んでいたけどクリアしたのでレビュー 2002年に出たゲームと言えどSTGとしては微妙だと思いました 見にくい敵弾、忙しくスクロールした割に何もないなど敵が出ない合間がちょこちょこありゲームテンポが悪い、 赤を取っていればすむパワーアップ、出過ぎるため取得して育てる意義が感じられない勲章システム… 良かった点は描き込まれている登場兵器の数々くらいでしょうか エクステンドが無くボム仕様時の無敵時間も一瞬で初心者にも優しくない… ゲーム内容が残念でこれではとても王道とは言えないでしょう
This game is more like Raiden sequel than XII Zeal sequel. It was rebranded into Zeal series simply because it was made by the same company. So, if you like Raiden, you may like this game. Can save replay. Have online leaderboard. Can view replays from online leaderboard. I saw two replays that seems to not be a valid replay, but their scores are close to the valid top score. Either hacked or desync'ed. The game starts with 3 credits and it will increase the more you play. It seems the maximum is 9 credits. The original arcade name is called G-Stream G2020 in case if you want to emulate it.
Fun shooter that is ruined by one fatal flaw. As other reviewers have mentioned, certain enemy bullets are nearly impossible to spot. Whose genius idea was it to make the enemy bullets blend into the background? This often results in sudden deaths that are nearly unavoidable unless you have eagle eyes. Ultimately, Deltazeal is a fun shooter that will take a huge dump on you with it's, all too common, cheap shots.
There’s so much to commend about this one—the gorgeous pixel art, the catchy soundtrack, the varied routes both between stages and within them. The stage 6 background might be one of my favorites in any shmup—a dense cityscape turning to night as you battle a massive enemy battleship. Unfortunately the bullet visibility issue is such a fundamental problem that it makes recommending this one impossible for me. They simply blend in with everything—the backgrounds, the medals, your own shots, the explosions effects, the debris that flies off destroyed enemies. They are also quick and have a tendency to flash, which makes tracking them more difficult than it needs to be. You won’t notice this in the screenshots, where they look solid and easily readable, but in game they’ll come at you so covertly and so fast that panic bombing isn’t even really an option much of the time. Triangle Service’s later shmups Trizeal and Exzeal do a good job of fixing this issue, but sadly that doesn’t help this one.
I love it!
One of the best shmups on Steam!
Muy buen Shmup/STG. Entretenido. Te va aumentando la cantidad de continues según el tiempo que lleves jugando. Tiene niveles alternativos de acuerdo a como juegues y dentro de cada nivel variaciones del mismo. El sistema de PowerUps también es bastante entretenido. Cuenta con bombas y un disparo secundario especial de uso estrategico.
a cool retro-style shooting game, must play
Awful presentation and menu system. Unplayable in full screen mode. So pathetically bad that, if it were free, it wouldn't even be worth the energy you would spend to click the button to add it to your account.
