The rules are as pure as the classics: steer your cruiser left and right while it auto-drops depth charges below. Your job is to survive as long as possible and rack up the highest score before an enemy rocket sends you to the bottom. WHAT'S WAITING BELOW THE SURFACE: Auto-dropping depth charges — you just line up the shot Enemy submarines that fire back with rockets A devastating super bomb — save it up, then detonate at the perfect moment A rare golden submarine — sink it for a bonus life Upgrades and extra lives, bought with coins you earn in-game Rising difficulty — the deeper you go, the hotter it gets Fully localized in English, Polish, German, Spanish, and French No sign-up, no connection required to play — just pure, one-more-try arcade action made for your phone. How high can you climb before your cruiser goes down? Dive in. Lock on. Sink 'em. Zasady są proste, jak w najlepszych klasykach salonów gier: sterujesz krążownikiem lewo-prawo, a on sam zrzuca bomby głębinowe. Twoje zadanie? Przetrwać jak najdłużej i zdobyć jak najwyższy wynik, zanim wrogie rakiety Cię dosięgną. CO ZNAJDZIESZ W GRZE: Bomby głębinowe zrzucane automatycznie — Ty tylko celujesz Wrogie U-Booty, które odstrzeliwują się rakietami Super bomba o potężnym zasięgu rażenia — zbieraj i detonuj w idealnym momencie Rzadka, złota łódź podwodna — zestrzel ją po dodatkowe życie Ulepszenia i dodatkowe życia za zdobytą w grze walutę Rosnący poziom trudności — im dalej zajdziesz, tym gorętsza akcja Pełna lokalizacja: polski, angielski, niemiecki, hiszpański, francuski Żadnych rejestracji, żadnego internetu do samej rozgrywki — czysta, arcade'owa zabawa, jakiej brakowało na Twoim telefonie. Ile punktów zdobędziesz, zanim krążownik pójdzie na dno? Zanurz się. Namierz. Zatop. Die Regeln sind so klar wie die Klassiker: Du steuerst deinen Kreuzer nach links und rechts, während er automatisch Wasserbomben abwirft. Deine Aufgabe: so lange wie möglich überleben und den höchsten Punktestand erreichen, bevor dich eine feindliche Rakete versenkt. WAS DICH UNTER DER OBERFLÄCHE ERWARTET: Automatisch abgeworfene Wasserbomben — du zielst nur Feindliche U-Boote, die mit Raketen zurückschießen Eine verheerende Superbombe — sammeln und im perfekten Moment zünden Ein seltenes, goldenes U-Boot — versenke es für ein Extraleben Upgrades und Extraleben, gekauft mit im Spiel verdienten Münzen Steigender Schwierigkeitsgrad — je tiefer du kommst, desto heißer wird es Vollständig lokalisiert in Deutsch, Englisch, Polnisch, Spanisch und Französisch Keine Anmeldung, keine Internetverbindung zum Spielen nötig — einfach pure Arcade-Action für dein Handy, bei der man immer "nur noch eine Runde" spielen will. Wie weit kommst du, bevor dein Kreuzer sinkt? Abtauchen. Anvisieren. Versenken. Las reglas son tan claras como las de los clásicos: manejas tu crucero a izquierda y derecha mientras suelta cargas de profundidad automáticamente. Tu misión: sobrevivir el mayor tiempo posible y conseguir la puntuación más alta antes de que un cohete enemigo te hunda. LO QUE TE ESPERA BAJO LA SUPERFICIE: Cargas de profundidad automáticas — tú solo apuntas Submarinos enemigos que responden con cohetes Una devastadora superbomba — guárdala y detónala en el momento perfecto Un raro submarino dorado — húndelo para conseguir una vida extra Mejoras y vidas extra, compradas con monedas ganadas en el juego Dificultad creciente — cuanto más lejos llegues, más intensa se pone la acción Totalmente traducido al español, inglés, polaco, alemán y francés Sin registro, sin conexión necesaria para jugar — pura acción arcade de "una partida más", hecha para tu móvil. ¿Cuántos puntos conseguirás antes de que tu crucero se hunda? Sumérgete. Apunta. Hunde.

Boom Karts Multiplayer Racing's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price and ads there is nothing between them.
