Let's see :
IceHold Normal [ human/wolves vs human/wolves] : You need to have a Basic Ice Wolf in your inventory which will allow you to transform to only Ice Wolf by pressing 3.
Same goes for Destruction Normal [ human/wolves vs human/wolves] , Conquest Normal [ human/wolves vs human/wolves] , Deathmatch Normal [ human/wolves vs human/wolves] , CTF Normal [ human/wolves vs human/wolves] , EX-Conquest [ human/wolves vs human/wolves].
Destruction S2 : [ human -red team vs wolf-blue team ] : You need to buy a 2nd Wolf mutation from the ex-item shop with 2000 gold [ it will automatically install , you don't need to install it ] and after getting some wolf points [ WP ] , after you get respawned you need to press Shift key to see the bar with wolves , and you have to choose between for wolves , other than the basic ones.
This is how it should look in the game:
This is how it should look in your inventory , what it says and that it has nothing to do with your tattoos :
This goes as well for Wolf War [ wolf vs wolf ] , Wolf Conquest [ human vs wolf ] , CTF [ human vs wolf ] Deathmatch [ wolf vs wolf ]
Video tutorial :
I couldn't choose any wolf from the mutation because I just started the game and I had no kills , therefore no WP.
If you need a better quality , tell me.
*I saw you've been asking for this issue for kind of a long time , I hope this finally helps , if not , I don't know what's wrong.
