Untouchable Trophy in Real Boxing
Win a fight and don't get hit.
How to unlock Untouchable
This can be tough to get before you have max stats, if you're not very skilled. Your opponent cannot land a hit in the whole fight. If it hits your guard it doesn't count. When you have upgraded all stats to max it should be pretty easy to get in the first fight of Roosters Tournament.
When the fight starts, immediately raise your guard by holding to avoid a cheap shot. Be aggressive but be prepared to dodge (just tap ) and then counter to quickly drain the opponents strength. If you take a hit just exit the fight and restart.
