quite simply, upgrade your handgun (glock is excellent. Full auto :) ) until you can get an SMG, beef that up, and at some point, you should be able to get the m14. Make sure to buy clip upgrades!
if the game is hard for you, you fail. By setting up a handful of blasters to keep a good perimeter, you stabilize. Other tips: MORTARS and TURRETS MOVE
Well, fun game and all....but the difficulty on normal is absurd. Between wave 0 and wave 1, you go from a few enemies, to a bunch of them. From wave 1 to 2, you go from a bunch, to a wall of enemies that require two hits. And then just walls. the handgun is too bad, and too expensive to upgrade. During reload I'll lose 2-3 structures.
antonio: Well, the point was to make a very similar thing to advance wars. He spriced it up, and you aren't the first idiot to score him down for making a copy of a game you apparently enjoyed.
if you use the nuetron bomb, then there are a few survivors. Nuke totally destroys the city.
Vegas is wierd. By the time I noticed it was infected, everyone was immunized or dead.
Really fun game, but the controls feel unresponsive. Passing takes a month (often ending with the other team getting the ball) not to mention that when you try to pass the ball to the goal from up close...... you pass it to your goalie. (Maybe slide over the non move controls over to the left. F is useless right now)
