Our team is working on straight port of this game to PC! ... As for quality of our port - be calm, we are re-creating all missions based on decompiled bsp's of original Decay with minimal improvements. PC version will also feature all the upgraded models and will be available for both WON and Steam versions of Half-Life.

Like Gearbox's other expansion packs Opposing Force and Blue Shift, Decay returns to the setting and timeline of the original story, but with different player characters: two female colleagues of Gordon Freeman, Dr. Gina Cross and Dr. Colette Green, who both take part in the Anomalous Materials laboratory experiment - they make preparations for the experiment under the Test Chamber such as monitoring Anti-Mass spectrometer and delivering anomalous materials to Dr. Freeman. When disaster happens both women together with their collegues Dr. Rosenberg and Dr. Keller try to save personell of the facility and reverse the resonance cascade to seal the dimensional rift.
