Pentapus

Players move a weapon, a Stargate, which is able to fire projectiles to defeat enemies, but is also vulnerable to bombs and has five lives. The game contains four difficulty levels of play, from K to 1-3, with the K level featuring slower paced gameplay designed for children. In each level, a player must defeat three waves of enemies, and then defeat the Pentapus. The game is compatible with a joystick, features a pause system, and allows high scores to be saved and written to the disk.

Pentapus received mixed reviews. Positive reviews praised the novelty and challenge of the game. Creative Computing stated Pentapus was an "exciting game" that featured "great sound and graphics" with "interesting twists to the arcade format". Writing for Electronic Games, Rick Teverbaugh praised the game's imagination, stating that although the game "owes its look to Galaxian...there is just enough new strategy (to) keep even the most accomplished Galaxian player befuddled.

Some reviewers were mixed on the strengths and weaknesses of the game. While Jeff Hurlburt for SoftSide Magazine found the game to be "an attractive, slickly presented game", he also stated "experienced arcade players may be disappointed", noting the "implementation of the stargate weapon leaves much to be desired. Movement control is very sluggish. The stargate responds as though attached to the paddle with a set of rubber bands."
