Extreme Rise of the Triad

Many players wondered how Apogee would follow the success of Wolfenstein 3D in 1992. The answer was "Blake Stone: Aliens of Gold"! Where Wolf3D took you into the past; thrust into a world at war - Blake rockets you into the future where a sinister madman, Dr. Pyrus Goldfire, is using genetics to create an army of bizarre creatures and wage war on Earth.

In "Planet Strike", once again, British agent Blake Stone will find himself in a life or death struggle for the control of humanity´s future. After a five year manhunt for the elusive Dr. Goldfire, the search has finally ended on Planet Selon at the abandoned STAR Institute Training Complex. If the reports are correct, then Dr. Goldfire is alive and has once again created a fiendish army of evil mutants. Blake is going to need all his wits, skill, and the best firepower money can buy to put an end to Goldfire´s plans.

"Rise of the Triad" thrusts you into the world of an elite group of operatives called the HUNT (High-Risk United Nations Taskforce). Together you must stop a maniacal cult leader from killing millions of people.

While scouting a remote island, you are suddenly surrounded by enemy troops with guns blazing. In the distance you see your boat--your only chance to escape--explode into matchsticks. In front of you is a huge fortress monastery, and your only way out... is in. You´re equipped with awesome, high-tech weaponry like heat-seeking missiles, split missiles, and the Flamewall cannon, which leaves a trail of charred skeletons in its wake. You´ll also find magical instruments and weapons so incredible they defy description.

"Extreme Rise of the Triad" ups the ante with over 40 new levels as the HUNT returns to take on even more maniacal Triad madness. Not enough for you? There´s even a RandROTT level randomizer so the ludicrous fun never ends! What are you waiting for?!
