Enjoy the nostalgia of this classic game re-created in the original style of the TI-99/4a computer game from the 1980's!

Re-live the era with blocky but colourful graphics and simple but captivating sound effects.

You are the commander of the starship Parsec patrolling an alien planet. Suddenly, the on-board computer announces that you are about to come under attack by small alien fighters and large, heavily armed, hostile alien cruisers!

The fighters are highly mobile, and unless they are eliminated by your laser, they fill the screen, restrict manoeuvering of your craft, and may cause a deadly collision. The cruisers are highly aggressive and their armament devastating. Armed with photon missiles, they track your ship and fire on it. You must out-manoeuver and destroy them with accurate fire from your ship's laser. If you survive the waves of alien craft, do not let down your guard, for you also have to blast through an asteroid belt or refuel your ship, demanding the utmost in skilful flying.

Parsec is a challenging, exciting game packed with thrills. Danger and excitement are brought on with each new attack. Some of Parsec's features include:

- Waves of attack from seven different alien craft.

- Challenging flights through refuelling tunnels.

- Asteroid belts through which you must blast a path for your starship.

- Synthesised speech to warn of approaching alien craft or when it's time to refuel.

- Three different lifts to vary the speed at which the ship moves vertically.

- Increased difficulty levels to challenge you.

Parsec is a one-player game which tests your skills and strategy. Movement of the ship on screen may be controlled by on-screen controls or an MFI certified Bluetooth controller.

When the Bluetooth controller is used, the A button is for firing the laser and the B button alters the lift speed.

Scoring of points for destroying alien craft increases with waves and levels. Bonus points are awarded for successfully navigating an asteroid belt and refuelling.

Asteroid belts increase in speed and duration as levels increase. Extra ships are awarded at certain score levels throughout the game.

Great port

It’s an excellent recreation of this great TI game.

In level 2, the bynite ships disappear before they are destroyed. I don’t recall that happening in the original game.

On my iPhone X, the control “stick” gets stuck if you move your thump outside of the circle. It would be great if the control provided some type of haptic feedback when you’re at the movement limit.

Hi and thanks for the feedback. The Bynites are meant to go invisible on level 2 after you hit them once. That's definitely how the original worked, I've double-checked. I will make note of the issue you reported on the iPhone X with the on-screen joystick. Thanks again!

Upgrade Support Needed

I absolutely love this app. Ah, the memories it brings as a young kid paying this game with parents, siblings, and friends back in the 80’s on our “new” Texas Instrument game consoles. Thank you for creating this app to allow such wonderful memories to resurface! To my dismay, with the recent iPhone and iOS upgrades, there’s a screen resolution issue causing the bottom portion of the game screen not to be visible. I’ll continue play occasionally on an older phone as long it’s still operational. My fingers are crossed the developers will do an upgrade allowing us nostalgic players to once again play to our hearts content on more current platforms. Thank you again for creating this app and letting us re-live such childhood memories!!! Let Parsec live on!!

Faithful Recreation of a Classic Game

The TI 99/4A was my first computer, and Parsec was my favorite game on it (though I didn't have the speech synthesizer). This game is a spot-on recreation -- right down to the littlest details in the scrolling terrain and the way that only one sound effect can be heard at a time.

It would be nice if the game would keep and display high scores. Also, the "joystick" can be twitchy (often when I slide it to go up, it starts off by moving the plane down before correcting), particularly on the smaller phone screen as opposed to on a big iPad screen. But these are mere quibbles. Five stars for the sheer joy of being able to relive happy childhood moments!
