Last mission of Americans: Winning easy
     When  John finishes talking you and 4 other men walk to the hill,
if you can kill one before he becomes under your command then you will
not be attacked by anyone as this is a glitch, also you can build your
base inside the Allied base and not be sent off, =)

P.M. Belkov's relative
     In  the  first  Russian mission, allow P.M. Belkov to die. In the
next mission his relative I.M. Belkov will appear. Note: Sometimes the
game will glitch.

One On One mission: Easy completion
     Have  John Macmillan in a heavy gun turret on the hillside to the
east  of  the  base.  Have  Joan Furgusson do everything. Also let her
train apemen for the crates.

     A good way to invade someone's base is as follows:

American: Lots of heavy gun tanks

Gameplay Tips:
     Armories  make  excellent defensive structures early in the game.

     Mechanics  get a double level bonus inside vehicles, and soldiers
get a double level bonus inside weapon turrets.

     Characters can reach a maximum level of 10 for each class.

     The heavier the tread, the better the defense for vehicles.

     An upgraded depot gets a wider sphere of influence.

     Soldiers  are  useful  early  in the campaigns, but mechanics are
best by the end.

     Oil power plants cause a constant drain on your oil reserves, but
a  single  oil  drilling  tower  can  support  three oil power plants.
Meanwhile,  solar  and  Siberite  power plants only require a one-time
fee.

     During  in-game  cinematics, you can still use the numpad "+" and
"-" keys to speed up or slow down the proceedings, and you can use the
enter key to skip lines of dialogue.
