It is how the original should have been released. Ammo conservation, way points, level editor, etc. I gave up on the campaigns in the original. The only problems I have with this game are the no in game saves and the fact that you have to have the original game on your computer to play with others using the original. So you have a nice big chunk of space taken up just so you can play online.
Most people play online with the original.
The 10th time you replay a mission because a tank got a lucky shot on your mech piolet's cockpit, you'll start getting ticked. The sound is good. The game has a great storyline. For the original campaign, you have to clear out an area for the primary invasion force to land. You start out with a few mechs and i believe 10,000 resource points.
