Notes:

Numpad 1: Mega Infantry Unit - it's best to PAUSE the game first! Works only on INFANTRY UNITS that are out of vehicles. Click on a unit and then press this option. The unit will have massive HP and most things cannot kill it. Note that the health bar may not change immediately, or may turn yellow or other colors during battle, but generally the unit is invincible for the rest of the mission. Use carefully and do not use unless the game is paused to prevent the AI from getting this advantage. You can unpause after affecting units and control them normally.

Numpad 2: Unlimited Ammo - toggle on and most weapons and vehicles have unlimited ammo. Will not REPLENISH ammo, but will prevent ammo from being USED. Best to toggle on and beginning of missions.

Numpad 3: Add Vehicle Fuel - select a vehicle then press key to affect it.

Numpad 4: Add Vehicle Spare Parts - select a vehicle then press key to affect it.

Numpad 5: Ignore Command Points - toggle this on in the mission planning where you can select which units to bring into battle and you can bring as many as you like without running out of command points.

Numpad 6: Ignore Unit Caps - toggle this on in the mission planning where you can select which units to bring into battle and you can bring as many of TYPES of units you would like, even if there is caps on a certain number of that unit. Note that the game may try to put all these extra units into places on the map that you can control them but they are 'stuck' so use with that info in mind.
