Star Journey Tactics

Star Journey Tactics is a space combat, turn-based-tactics game. This is a game I've been developing as a prototype. It's nowhere near finished, but I've gotten it to a point where I actually have fun playing it, so I'm posting it for anyone else who wants to play and give feedback. A lot more to come.

Jug

You are an interactive humanoid composed of Titanium fleximetal and other organic materials, first built in 3642 AD - nicknamed 'JUG' because of your barrel chested profile which can transform into many different shapes and reform instantaneously. The task is simple- This is your 14th Tour of Duty and within the living core of the Planet Spiraeus, is a deadly virus causing its brain to malfunction and all the inner sanctums to die as the life force is diminished. This planet is divided into four zones, each of which has four sectors. Trap doors in the floor and holes in the roof will enable you to move up or down a level. You must find and destroy the deadly 'tumor' within the deepest parts of the planet, before it becomes an empty shell drifting in the depths of Space and Time. Warning!- The planet's immune system will see the Jug as a hostile and alien body so you will be attacked by the defense system of the very planet that you are trying to save! Vital equipment will be transported into the planet along your proposed trajectory to help you in your quest, and fuel pods will be available throughout the game. But take heed, the problems will really start when you have reached the source of the disaster... With be-directional scrolling, parallax scrolling and the most stunning graphics possible on the Amiga, you must surely agree that JUG is a game that no one should be without.

Goldrunner

In Goldrunner, a vertically scrolling shooter, earth has to be evacuated because of the damage caused by environmental pollution. Unfortunately the space ships have to pass through the world of Triton - and the inhabitants are unfriendly. So the obvious solution is to destroy the rings, huge space stations. A full frontal attack is without a change of success because the rings have to be destroyed from within. So the player is chosen to man a small space ship to do the job. Every ring has a certain amount of energy which has to be reduced by destroying everything inside. Of course the Tritons won't give up without a fight, but touching the enemies won't hurt the space ship (it hurts them): the only way to die is by touching enemy mines (the ship can take up to five hits) or by flying against a high, indestructible building (instant death). The ship also has a turbo boost function and between levels there are bonus rounds which are used to rack up points for the high score list.

Alien Protect

Missile Command, inverted. Earth's private space programme is launching hardware across the solar system, and nobody is enforcing planetary protection. You are the quarantine officer who does. Three defence batteries. Limited ammo. Nothing homes, nothing locks on -- you lead the shot yourself and detonate where the rocket is going to be. Named, inhabited worlds burn one at a time if you miss, and Earth learns from every wreck it recovers, so escalation is your own leftovers coming back at you. Classic Arcade is the ranked ladder: a fixed loadout, endless waves, crisis spikes and breathers. Mastery tokens, the codex and your high scores persist between runs.

River

The great collapse could be traced back to an event in 2068. The Last Rain, or so they call it. When one of the most fundamental cycles of our planet broke, the world followed suit. It wasn't just the thirst that killed us, not society caving in under the scarcity of a necessity, nor was it clawing hunger that finally settled in, but it was the realization that the earth had finally given up on its most populous parasite. Riots became wars, and wars became silence. Until merely chasms of nothingness were left. When the sky turned into a blazing ball of heat, humanity did the only thing it could. It crawled back into the dirt. Desperation begets creation. Humanity's greatest quality was its ability to produce magnificent things in the most trying of times. Hidden within the cracked remnants of what once were thriving wilderness, Dr. Arthur U. Lan built a grey sanctuary. He surrounded himself with the hum of machinery and the ghosts of a dying planet, obsessed with a single, impossible task of fixing the broken parts of nature. But tragedy was destined to fall as all things created will eventually become twisted Year XXXX. Deep within the cooling metal of an abandoned bunker with no recollection and a wiped system unit, Model G5-R17 flickers to life. Guided only by fragmented logs and encrypted data found along the way, G5-R17 must navigate through the desolate remainders of what once was a beacon of hope and find out what happened to the mysterious voice behind all of the logs saved, Arthur. What truly happened all those years ago? Will Arthur's mission finally come to fruition or will it pitter out along with the rest of Earth's existence.
