Numpad 2: Cut AI Supply Lines - toggle on and when the AI tries to build things, it has no credits.

Numpad 3: Player Invincible - toggle on and team 1, usually the player, is invincible.

Numpad 4: AI Invincible - toggle on and team 2, usually NOT the player, is invincible.

Numpad 5: Carnage Mode - toggle on and the damage is massive.  Almost everything is killed instantly.  This includes ALLIES and YOUR TROOPS.  To protect YOUR troops, use the Invincible option.  The invincible option will not protect allies from damage so only use this if it is you vs AI enemies.
