About 异界炮艇

This is a fun shooting game that includes tower defense elements. You will control an air gunboat equipped with three main types of weapons and several powerful special weapons. And leap your army to defeat thousands of monsters from other worlds.

Background story

Humans have discovered abandoned alien bases and portals on the far side of the moon, obtaining teleportation technology from them, but at the same time activating portals. While they can travel to other unknown planets, portals left by other aliens can also reach Earth. In order to prevent invasion, countries formed a joint army to explore and mine unknown planets first. An aerial gunboat is built using the latest technology to serve as an aerial firepower fortress and command center, establishing a transition base as the vanguard force.

Gameplay Introduction

Players will play the game from the perspective of an aerial gunboat, with three types of main weapons to unlock and choose from: rapid fire guns, secondary guns, and main guns. There are also powerful special weapons that share energy.

After killing a certain number of enemies or defeating bosses, you can select upgrade cards to use to upgrade gunboats or jump your troops. The troops include various options such as armored vehicles, tanks, helicopters, rocket launchers, etc.

You need to protect the base car located in the center. If the base car's health drops to zero, the game ends. As time goes by, the enemies will become more and stronger.
