|Description||Reach the rank of 'Lone Wolf'|
|Orb Points||500||Orb Coins||5|
This is quite a hard achievement, because for free players it can only be done on hard mode.
Have 'Hard mode' unlocked (beat the game on 'Normal mode').
Beat the game on 'Normal mode' a couple of times so you're experienced enough to do it on 'Hard mode'
Starting on 'Entrance' and going as fast as you can, destroy the mines to the north, and then run straight to the other mines, to the southwest. Kill all the aliens that come at you. Quickly destroy the mines. This should give you the rank "Squaddie" or even "Engineer" if done fast enough. Take the C.R.A.G., and then play out the game like you would normally do. This is a very good tactic because now you've already reach the 5th or 6th rank, so you will only have to get 5 or 6 more ranks. Normally you could have reached "Lone Wolf" in level 9 ("Regicide") if you killed most of the aliens on all the previous levels.
NOTE: The maximum rank for f2p players on hard mode is rank 14, "Elite Hero", but this is extremely hard, and you have to kill almost every alien on each level.
