Cosmic Guerilla
宇宙游击队
Cosmic Guerilla is an arcade action game released by Universal in 1979. Players control a cannon at the bottom of the screen and must shoot upward at waves of alien invaders arranged in formation. The gameplay involves moving the cannon left and right while firing at enemies that descend toward the player. A notable feature is the destructible bunker shields that provide temporary cover but can be worn away by enemy fire. The game supports two players taking turns. Enemies move in patterns and increase in speed as their numbers decrease, raising the difficulty progressively. Cosmic Guerilla follows the fixed-screen shooter format popularized in the late 1970s, with the goal of clearing each wave before enemies reach the bottom of the screen.
