Got this game as part of Origin's free games. The topic is interesting and I like revisiting old games, back up to the 80s. This one did not age well. Despite modern hardware which performances were unheard of at the time, the game is STILL slow to load. Graphics do not scale up to current monitors native resolution. But more importantly the game engine is quite frustrating with clipping issues, line of fire not starting with the gun as displayed on your screen (i.e. rocks next to you will act as in front and block your shot), enemies will appear in the middle of nowhere, literally drop from the sky into pre-scripted locations, path is narrowly limited to the scenario leading to idiotic approach angle of enemy encampment. Even as free I recommend to pass and spend your time on something else.
