the trick to the game is fully upgraded bazooka,
production, and endurance...then just fill the
screen with bazookas and overwhelm any enemy. I
never even built a single tank and only used
helicopters for level 5 just to get the bonus
here's a few tips. the first gun you buy
should be the M4 (high rate of fire, quick reload
and reasonable damage), buy it after day 3, till
then you can get by with 9mm, no need for
barricades. The next gun, should be the Barret M82
(piercing...so it scores hits on multiple targets
with a single shot). These are the only 2 guns
you'll need for the game...buy mercs now. The
trick with the 2 guns is this...the M82 takes 1
second to fire...in that same second, the M4 fires
6 times. Use them together! as soon as you fire
the M82, switch weapons and fire off a few rounds
with the M4, then switch back for your next M82
shot. I get 1 M82 and 3 M4 shots/second. Like
having an extra merc. just pay attention to
reloads...
