Nick Laurant, an avid air soft competitor, provided most of the costumes and some of the guns himself.
All of the guns were air soft replicas, mostly bought off the Internet. John Latham accidentally broke two of them during filming - both in only one scene.
While filming the scene in which the CORPS soldiers rush the entrance of the rebel base, Matt Kummerfeldt cut his leg when he fell to the ground after being shot. Fortunately, Lucas Pernell and Nick Laurant had experience in administering first aid.
Most of the film was shot in an abandoned building that was actually rather unsafe in places. Fortunately, few injuries were sustained during filming. All of the items seen in backgrounds (desks, chairs, phone booths, etc.) were as the crew found them when they arrived to film.
Shot over a period of two to three months, on weekends and holidays. Post-production took much longer, due to the large amount of special effects.
