[Name] T-Abyss Virus [Source] Resident Evil: Revelations [Symptoms] 
A variant of the T-Virus, designed by FBC CEO Morgan Lansdale to show the world the dangers of bio-weapons and increase his own personal power through use of the 'Veltro' terrorist group. The virus crates zombies and BOWs who are strongly linked with water, and have numerous aquatic features such as tentacles and crab-like shells. It is encountered in the game when 'Veltro' threaten to infect the world's oceans, hoping to exact revenge for the loss of much of their forces during the bio-terrorist attack on the floating techno-utopia Terragrigia. It is encountered during exploration of three research vessals, where it has transformed the crew and several sea creatures into zombies, mutants and Tyrants.
