To be honest I liked the set up of Moonwalk from a couple years back up at Muskoka Primary.
Instead of fixed objectives, you just had two forces in the field attempting to destroy eachother. Throw in a few modifiers (IE capture/control a SAM site and your respawn time is cut in half since you can use helis), stuff like that, and Wham, great game day.
Maybe you'll find someone else to help you. Maybe black mesa... THAT WAS A JOKE, ha ha, fat chance.
