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. 这是一个街机风格的潜艇游戏。本场比赛的目的是，摧毁每个级别上所有的潜艇推进到一个新的水平。你的船从后面投下深水炸弹，摧毁潜艇。深水炸弹爆炸损坏潜艇旁边。深水炸弹爆炸所处的级别触摸屏幕。 正如你进步，在游戏中，你可以赚学分，以帮助您完成您的任务，升级你的船以下： - 减少深水炸弹负载时间 此次升级将减少花费的时间量的船员加载到发射深水炸弹。当你需要更频繁地发射深水炸弹，选择此升级。 - 增加航速 此次升级将增加船的行进速度。当你需要能够赶上潜艇的速度，选择此升级。 - 增加深水炸弹 此升级是非常有用的，当你无法完成的任务，因为你一直运行深水炸弹。注：此升级是没有效果，而不必首先减少深水炸弹加载时间升级。 - 增加负载深水炸弹 此升级是非常有用的，当你需要有更多的深水炸弹加载和准备推出。注意：此升级是不是有效的，除非你有缩小深水炸弹加载时间和数量增加深水炸弹升级。
