Power Strike, known as Aleste (アレスタ) in Japan, is a shoot-'em-up by Compile released in 1988 by Sega for the Sega Master System. It is the first game in Compile's Aleste series of shoot-'em-ups. Compile released the game to the MSX computer in Japan.

In North America, Power Strike was initially only available through mail order from Sega, but it eventually had a limited retail release. While the MSX game received two sequels, Compile would take the franchise further on other platforms through 1994. Most Aleste games released outside Japan would use the Power Strike moniker, with a few exceptions (MUSHA, Robo Aleste, the SNES game Space Megaforce). The Master System game was followed by Power Strike II in 1993; this is an outlier in the series and was only released in Europe.

Story

In Space Year 6180, the planet Rimar entrusts its environmental maintenance to the supercomputer DIA51. One day, while DIA51 is genetically engineering a new plant for oxygen synthesis, a massive earthquake occurs that causes DIA51 to malfunction and alter the DNA sequence of the plant.

A month later, DIA51 begins to go haywire, severing communication with the military base in which it is located, and the temperature of the planet begins to rise. The planetary defense forces learn that DIA51 is creating intelligent plant life to infect human brains, and they dispatch the advanced Aleste fighter to eliminate the DIA51.

Gameplay

The game is a vertically scrolling shooter. The player pilots the Aleste (or the Power Strike in the English localizations), which is moved in any direction with the D-Pad. The Aleste is equipped with a standard pulse beam that is fired with and a special weapon that is fired with . Either can be held down for continuous fire. Both weapons have unlimited ammunition and can be fired simultaneously. The standard weapon can be upgraded by collecting Power Chips. The special weapon can be switched or upgraded by picking up numbers corresponding to each weapon. All of the special weapons except the first, which is initially equipped, only last a certain duration and revert back to the starting special weapon once their timers run out.

The Aleste is destroyed if it takes damage from an enemy, costing the player a life. The ship respawns after a moment, but the player loses any power-up effects after losing a life. The game ends if the player runs out of lives, but it can be continued from the title screen as long as the player has continues remaining. The player gains an extra life at 20,000 and 100,000 points and then every 100,000 points after that.
