Thing Thing 4 (Spoiler Warning)Edit
Project 154 escapes from Vahl Dreig's containment room on a quest to find the person who made him/her into a bio-weapon, so he/she may get his/her revenge. On his/her way he/she runs into Project 153 who tries to kill him/her in an attack helicopter, but ultimately fails and is apparently killed when it crashes.
Nearly at his/her destination, Project 154 runs into Project Hades, one of the most powerful bio-weapons ever created. After defeating Hades, Project 154 moves into System Corps' main office, only to find the CEO is not present. The CEO appears on many screens and makes a long speech to 154 before removing his/her healing factor with a strange gas. 154 is then ambushed by countless waves of SystemsCorp employees, which he/she has no chance of stopping. When 154 apparently dies, you hear the CEO tell someone to get their buyers on the line because they have "worked out the kinks".
