|Description||Complete the game without recruiting any new soldiers on normal difficulty|
|Orb Points||1000||Orb Coins||10|
Using only the initial 4 soldiers is easier than using all 12 as by the near end your soldiers will be very hard to kill and extremely accurate, but either option is allowed as long as soldiers aren't replaced if they die. It is recommended to restart your mission at any time if you are using four soldiers and one of them dies.
On act 4, just run. Don't worry about aliens unless they're blocking your way, are endangering the person with the nuke/data, or you really have time and it's only one! If you do this, the hardest part is finding the stairs. Restart if any soldiers die in 4-2, but don't in 4-3 because even one soldier with the data will let you win.
Note that this MUST be done on Normal and only on normal, you will not get it even if you do manage to do it on Hard (which isn't impossible, just more difficult for the average player).
