That said, Apex is not a terribly sophisticated variation on the time paradox story. One can pick all manner of holes in it it is never clear how the story can progress from one person going back in time and destroying a rogue sterilisation unit to an entire army of sterilisation units engaged in a war against the human race where did all the other robots come from? Nevertheless, the time paradox storyline is reasonably well done and the characterisation is better than average. There are some effective moments, particularly during the scenes where the hero suddenly has to step into an existence he has never known before discovering for the first time the details of a life as he enters his room, searching out his wife but finding her a different person to the one he knew in his timeline.
Apex is also similar to director Phillip J. Roths earlier but less interesting Prototype X29A (1992), which had a similar decayed future look and a plot where humanity was engaged in a last ditch war against two different species of robots, one created to destroy another type of robot that had gone out of control.
Odd trivia note: If one looks carefully in the background of some of the alternate future scenes they can see the old Landmaster vehicle from Damnation Alley (1977) cruising about.
