This is not The Expendables. More like Thunder in Paradise TV pilot, but cancelled. By the way, Showdown is directorial debut of martial arts legend Mark Dacascos. Doesn't sound good, right? Two lead actors are ok. Casper is underused master of suspense acting, Alexander is big and calm guy. I would surely watch TV series based on this detective duo, but the movie itself is too short and feels unfinished. Couple of scenes with legendary action stars doesn't help much. Nevertheless, I give 5 for beautiful nature of Philippines and another 5 for the nostalgia. 10/10.
