In 1982 my friend Dan Thompson came up with the basic idea for Repton taking some inspiration from Defender. Since he was working on another game he told me I should do the implementation. I wrote the Apple II version and later he did ports to the Commodore 64 and the Atari 800. It was well received and for the six months that Sirius Software continued to be in business it sold well.

I wanted to do an iPhone game and I’ve long wanted to bring Repton out of the siliceous relic that is 6502 assembly language. Starting from memory this is a recreation of my first arcade game. I hope you have as much fun playing it as I have had writing it for the iPhone.

If you want an idea what the original looked like - go see Jeff’s Repton Tribute site.

Repton Mission Orders

They came out of nowhere and destroyed the mining operations in Farsystem. The attacks overwhelmed meager planetary defenses designed for rougers. Unified Colony response has been quick. The Repton Armageddon Ship is our newest defensive weapon system. The RAS incorporates turbo pulse lasers, the new Mark III hyperdrive, tactical fusion weapons, auto shields, and in-dash music player.

We have very little strategic information, and only the following tactical information.

Moderately armed. Workers build the enemy base. Do not let them complete the base!

Sensor platform with no known weapons. They can seemingly disappear among buildings when at low altitude.

Able to tap planetary power grid. The RAS can recover power by intercepting the beam. Power can be returned to the grid via the Power Tube, or in a pinch it can be used in place of a nuke bomb.

Very dangerous with long range energy beam weapons, but limited to short duration periodic fire.

The Minelayers have only been observed laying short duration mines.

Cluster-Ship
Slow but dangerous as it comprises four Single Ships. They are moderately armed.

Single-Ship
The most effective of enemy resources, it is fast and well
armed.

The base can not be destroyed and it has defensive missiles. Completion of the base means the planet is lost.

Part of the planetary power grid they are critical to planetary defense. The stations are susceptible to the Drains.

Part of the planetary power grid. The RAS is able to exchange energy with the Power Tube. Energy captured from a Drain can be returned. The RAS can use this energy in place of a nuke bomb.

They come in waves with no end to the attacks once they begin. Your mission is delay and attrition until reinforcements arrive.

If not you cannot hold the planet you must leave them nothing of value behind.

Good Luck and Best Speed.
