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 Aug 4 → 0.14/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 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.

Versus shmup that feels the closest to a traditional arcade shmup out of this type of game I've played (compared to say Twinkle Star Sprites which is more puzzle-like and has a lot of unique quirks + neogeo slowdown). Single player is pretty solid too and there are difficulty modes to match any level of player. Multiplayer games especially on the highest difficulty can get really hectic with the bullet patterns resulting in fun improvised dodging. Highly recommended to fans of the genre if just for this. Netcode works nicely with input delay not being introduced unless you're controlling a boss form. You can easily play across continents with little issue, and bosses having their control nerfed is honestly justified for most of them. There is an equipment system which sounds bizarre but in my experience overall makes the game better. The baseline ships feel a bit underpowered to clearing out enemies. While if you are playing with powered up shot + return bullets (these cause enemy kill chains like TSS, or deal tactical damage to bosses!) you can get up to crazy enemy patterns as the game keeps getting harder the longer you survive. Super fun in PVP matches. For the past few years there has been a japanese & international group playing online every Saturday @ 9pm JST for a few hours. The longevity of that group should be some proof to this being a hidden gem of a game.

[h1]自分がボスになれる対戦型STG[/h1] 『ティンクルスタースプライツ』や『東方花映塚』のように、ザコ敵を倒した力を使って相手を攻撃する対戦型STG。 100%以上溜めたゲージを全部消費する事で相手にメガガン(大型ボス)を送れるのですが、メガガンの攻撃や移動の操作が自分でできるため[b]STGのボス気分を味わえる[/b]のが大きな特徴です。 (なお、スプライツや花映塚のようにメガガンの操作をCPUに任せるモードもアップデートで追加されました) メガガンから放たれる攻撃はとても強力なので、相手は劣勢になる事でしょう。 [b]しかしボムを使われたり、はたまた避けられメガガンを倒されてしまうと―――――[/b] たくさんのザコに囲まれてしまったり、相手からの反撃でこちらがピンチになる事も…。 ゲージを溜めてメガガンで一気に攻めるか、 それともチャージアタックで牽制するか。 リスク&リターンの駆け引きがとても楽しいゲームです。 発売から5年が経ち無料デモ版が公開されたのですが、1人用モードの2面まで遊べる他[b]まさかのデモ版でローカル&オンライン対戦対応[/b](※製品版とはマッチングしない)と 流石に選択できるキャラクター数は限られているものの、大盤振る舞いな作りになっているのでぜひ体験してみてはいかがでしょうか。 特にフレンドと通話しながらわいわい遊ぶのめちゃくちゃ楽しいです。おすすめです。 [h1]「製品版買ったけどオンラインマッチ全然しないな…」と思った方へ[/h1] 毎週土曜日の日本時間21時から有志が集まって遊んでる事が多いのでぜひ試してみてください!初心者の方も大歓迎です!一緒に遊べる時を楽しみにしています!!!!!
This is essentially Phantasmagoria of Flower View with proper controller support. I don't think there's more than I can say. Okay, for those who are unfamiliar with Touhou Project, Phantasmagoria of Flower View is a bullet hell concept where two players go head-to-head, with the main goal of the game being to get the other player to die from an overwhelm of bullet spam. To achieve this goal, you shoot down as much things as possible to build up a combo meter which in turn summons up portals on the enemy's screen to throw even more death at his or her general direction. On top of creating portals on the enemy screen, you also have chargable special attacks where you can spawn character-specific bullets rather than generic mooks to attack the enemy and at 100% meter, you can summon a boss on the enemy's screen! The main difference between Phantasmagoria of Flower View and Rival Megagun is that the boss is an actual player. Oh who am I kidding, if you're reading this review, you're probably a fan of bullet hell games and I strongly recommend this game for the merit of being a solid attempt into bringing the SHMUP genre into a PVP setting. Oh, and even if you have already played TH09, I still say that you should get this game because... A) The bosses are playable B) You can slow yourself down by gently tilting the analog stick C) Much better controller support than literally every Touhou game out there D) Setting up online matches for PoFV is a bloody chore. Steam integration is where it's at
Tons of fun, way better than TSS or PoFV. There's so many possible modes that are all uniquely fun, I lost count. I wish I knew the conditions for the Damage Up upgrade though, because when I play the German META, I'm at a disadvantage. Unless they agree to adjust the rules.
Un très bon clone de Twinkle Star Sprites sur NeoGeo, avec quelques améliorations ! Par exemple, dans Twinkle Star Sprites, le boss invoqué par le joueur était contrôlé par l'A.I. alors que dans ce jeu, c'est le joueur lui-même qui contrôle le boss et ses attaques. Evidemment, le jeu prend tout son intérêt à plusieurs, comme Twinkle Star Sprites à l'époque. J'ai ai joué un peu hier, en versus, et j'ai passé un excellent moment !
Vertical PvP gallery shooter. Score chains and defeat your opponent. Good ship variation with configurable loadouts. Play as a boss ship! Level up and collect gear. Awesome retro graphics and music.

GET IT.
Game is amazing; Netcode fantastic! Gen is OP 10/10 would get flamebroiled again
VICIANTE! Esse jogo é uma jóia rara. Fácil de aprender mas difícil de dominar, é muito intenso e as batalhas no PvP são simplesmente excelentes! O modo Story é bom pra praticar, mas a diversão mesmo está no PvP!
Rival Megagun is a fun multiplayer shoot'em up for local and online matches. It looks great and plays quite well. The single player campaign is alright but gets a bit repetitive, good for practice though. Multiple characters and game styles to choose from. Suitable for shmup beginners and experts.
