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): 0.14/day in the week to Aug 22 → 0.14/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.

Es macht wirklich sehr viel Spaß, ein bisschen schwer zum Anfang, aber wenn man die Upgrades hat Dann wird es halt immer leichter. Klare Kaufempfehlung
//!!!\\ NO CLOUD SAVE OPTION Gameplay is fine but content is not there. If this game take more than 2-3 hours to 100% is beacause you can only progress 3 "research" at a time. Without that, one game with every character and you're done. Also, at 13h I'm only missing 2 achievement, global money and kill, and I am at 1/10 for money and 1/7 for kills.
総合評価 SFとトップダウンシューターが好きならオススメ・・・カモ サバイバーライクがやりたいなら他のゲームをやった方がイイ いいと感じる点 ・値段に対するボリューム感 ・エイリアンの軍団と戦っている感 ・徐々にアップグレードを解放して強くなっていく感覚 ・周回プレイに彩を加える研究ミッション 微妙、ストレスだと感じる点 ・選択肢の再抽選は解放まで長いがバグっていて解放しても利用できない ・運のステータスを解放して選択肢が4つ出た場合は再抽選の解放状況に関わらず再抽選できてしまう ・不要な武器、強化の選択肢からの除外機能が存在しないので解放すればするほど好きなビルドが組めなくなる ・遠距離、突進、自爆、迫撃砲攻撃を行う雑魚敵が大量に湧いて来る上こちらの弾が派手過ぎて状況が把握できなくなり、蜂の巣にされる ・20分モードのボス敵が硬すぎる、第3ステージは固い上にジャンプ攻撃(使用中無敵)を超高頻度で行うため途轍もないストレスになる ・敵のAIは直進しかない、それだけならいいがステージ上にやたらと障害物がおいてあるので引っかかりまくる。第3ステージは沢山の壁で区切られた室内マップだよ、やったね!・・・2度とやりたくない

Game sucks ass - I enjoyed every second of it.
Not all that great. Hitboxes are pretty bad. weapons are basic without a lot of depth. Different characters give little to no differences between them.
Poorly balanced, frustrating to play, and clearly a lazy port of an already crappy mobile game. Feels like a total waste of time, not even worth a buck. Avoid.
