Ranger
Ranger is the latest game released by Netherland-based developing outfit, Foppygames. This one is another fun adventure platformer where you get to play a pilot on a reconnaissance mission against hostile and unfriendly aliens.
You'll need to navigate yourself through the many doors, looking for the hostages and rescuing them. At the same time, you'll need to defend yourself against the feisty aliens out to get you.
This game was created using Blitz 3D. There are also several other freeware games offered by the developer on his site so after you're satisfied with saving all the hostages as well as killing all the alien kidnappers in this one, go ahead and check out the others as well. Cool game that's worth your time.
