Press Start to pause game play in a campaign, then press R1(2), L1, R1, L1(2), R1, L1, R1(2), L1, R1, L1(2), R1, L1 to unlock the "Cheats" selection at the options menu. The cheat options include "Toggle Unit Spying", "Cheat Win", "Gimme $10000", "Show LZs", "Player Invulnerable", "Enable All Levels", and "Clear Fog Of War".

Select a campaign and play as the Marines , Predators , or Aliens. You will notice that more strategy missions will become unlocked as you pass by. However if you want the best reward, complete the campaign you have chosen and do all the missions with a gold medal rank. If you manage to get all seven gold medals in a campaign, a message stating that cheats can now be used in this campaign will appear. To use them, go to the options menu when you pause game play.

To earn the gold medals, you must do three things. Complete all optional and mission objectives and beat the target time. If you manage to do that, you will get a gold medal. Repeat this for all the missions to earn the cheats.

On the last Alien mission, enable cheat code and activate the "Toggle Unit Spying" and "Clear Fog Of War" cheats. The Predators on the level should show up as blue and the Marines should show up as the predator color on your mini-map.

Enable cheat mode. With a help of the Drone, start a Queen's Nest. Before you have her lay eggs, set her to "No attack" and get the maximum units that you can have (43 eggs, the Drone and the Queen). With the Drone, arrange the eggs in a way you can see all of them in the viewport (screen). Select all eggs and hatch them. The PlayStation 2 will freeze on a blue screen.

On the Marine mission 6, enable cheat mode and activate the "Toggle Unit Spying" cheat. Look for some hostile smartgunners. Their Smartguns should be pointed backwards.
