King of Boxer and open defense
In King of Boxer, you enter a sports match in pixel graphics. Reaction decides here: you read the swings, dodge and block regular blows. Accurate hits to an open defense interrupt the attack and accumulate a super punch (Super Punch).
How to start a fight
Immediately choose a jab or a straight punch so as not to give up the rhythm. J or Z throws a jab, K or X throws a straight punch. A/D or ←/→ takes you left and right, and W or ↑ holds regular hits. When your opponent makes a heavy swing, move to the side and look for a window to respond.
When to press super kick
The white star shows the window for interruption, and the same calculation of the move is needed in Ultimate Boxing: there they also hit an open block. A red warning means that the defense is closed, and it is better to dodge a heavy super strike. Space releases a super punch when charged.
How many opponents and belts?
You need to pass 12 opponents in three laps, and each lap keeps its own pace. For victories you collect three championship belts. After this, a battle with Iron Mike Dyson opens. Each new opponent gives you less time to react, so late matches require you to catch the defense more accurately.
When your opponent is down, alternate between Z and X to regain some health. This technique helps you survive until the next rounds.
