To kill Akuji in the teahouse, use L2 to counter his attacks. It does damage and knocks him down. When he is down, stab him twice quickly before he gets up. Repeat this until he has been killed.

To defeat Maero the first time on top of his hideout, hit him once with an RPG. When scoring a direct hit, he will go on one knee and stay down. You can then shoot him until he is defeated. If he gets up, just shoot him again. To finish off Maero in the arena, use some of the rockets to blow up all the trucks except for his. Use extra rifle ammunition to shoot his Monster Truck.
