This is an arcade style submarine game. The object of the game is to destroy all the submarines on each level to advance to the next level. Destroy the submarines by dropping Depth Charges from the back of your Ship. Depth Charges must explode next to the Submarine to damage it. Depth Charges explode at the level in which you touch the screen. As you progress in the game you can earn credits to help you complete your missions by upgrading your Ship with the following: - Reduce Depth Charge Load Time This upgrade will reduce the amount of time it takes the crew to load Depth Charges into the launchers. Select this upgrade when you need to launch Depth Charges more frequently. - Increase Ship Speed This upgrade will increase the Ship travel speed. Select this upgrade when you need to be able to catch up to submarines faster. - Increase Number of Depth Charges This upgrade is useful when you are not able to complete a mission because you keep running out of Depth Charges. Note: This upgrade is not that effective without first having the Reduce Depth Charge Load Time upgrade. - Increase Number of Loaded Depth Charges This upgrade is useful when you need to have more Depth Charges loaded and ready to launch. Note: This upgrade is not that effective unless you have both the Reduce Depth Charge Load Time and Increase Number of Depth Charges upgrades first. 這是一個(gè)街機(jī)風(fēng)格的潛艇游戲。本場(chǎng)比賽的目的是，摧毀每個(gè)級(jí)別上所有的潛艇推進(jìn)到一個(gè)新的水平。你的船從后面投下深水炸彈，摧毀潛艇。深水炸彈爆炸損壞潛艇旁邊。深水炸彈爆炸所處的級(jí)別觸摸屏幕。 正如你進(jìn)步，在游戲中，你可以賺學(xué)分，以幫助您完成您的任務(wù)，升級(jí)你的船以下： - 減少深水炸彈負(fù)載時(shí)間 此次升級(jí)將減少花費(fèi)的時(shí)間量的船員加載到發(fā)射深水炸彈。當(dāng)你需要更頻繁地發(fā)射深水炸彈，選擇此升級(jí)。 - 增加航速 此次升級(jí)將增加船的行進(jìn)速度。當(dāng)你需要能夠趕上潛艇的速度，選擇此升級(jí)。 - 增加深水炸彈 此升級(jí)是非常有用的，當(dāng)你無(wú)法完成的任務(wù)，因?yàn)槟阋恢边\(yùn)行深水炸彈。注：此升級(jí)是沒(méi)有效果，而不必首先減少深水炸彈加載時(shí)間升級(jí)。 - 增加負(fù)載深水炸彈 此升級(jí)是非常有用的，當(dāng)你需要有更多的深水炸彈加載和準(zhǔn)備推出。注意：此升級(jí)是不是有效的，除非你有縮小深水炸彈加載時(shí)間和數(shù)量增加深水炸彈升級(jí)。
