Odd cuase in Blue shift and OF they are found dead in spots in the Xen
Although the outcome for Cross, along with the rest of the survivors in Decay, is unknown, a body resembling hers can be found in Opposing Force by Adrian Shephard, in one of the Displacer's Xen teleport destinations. The actual model name for this body is gina.mdl (a Half-Life Deathmatch player model), which would suggest that the corpse truly belongs to Cross, "Gina" being her first name and the model existing since the release of Half-Life (and not Colette Green, since only the environment light is making the HEV suit look maroon, while it is clearly orange and beige). However, this possible retcon has yet to be made by Valve or Gearbox, since Gina Cross did not exist as a real character before Decay, released two years after Opposing Force, and that her fate is merely stated as being "unknown".
Also, Valve tends to reuse models, like the thousands of security guards that all look the same and sound the same, and some scientists tend to resemble other scientists you've seen before
Colette Green may be alive since in any of the Half Lifes, her body is never found, though i like to think that Gina Cross is also alive until Valve confirms who's dead and who isn't
