How to Make a Monster (movie, 2001)

Video game developer Clayton Software enlists the talents of a misfit group of programmers to develop the scariest computer combat game: EVILUTION. With four weeks to bring the game to market and a million-dollar bonus on the line, they utilize a telemetry suit to render a 3-D version of the onscreen player. But when a power surge gives the hard drive a mind of its own, the suit comes to life to play the game for real and the programming team find themselves in the middle of a chilling virtual nightmare beyond their wildest imagination.
