Initially, in this game kof 99, you chose four characters. The one you decided on the right-hand end is your striker. In the background, you hear the original kingoffighter-99 soundtracks. Visuals of the game are granular. For example, in the game, shadows are entirely seen on the wall. 

This is a tag team gameplay

Out of these 4 characters you chose, you can call anyone out for fighting. To boost your level bar, keep changing characters. This will allow your enemy to get maximum hits, and the striker will take care of the rest in the end.

The game has plots and story scenes. On passing every level, you get an instant boost on the level-up bar. You fight until you face Krizalid-the biggest enemy with ultimate power. If you succeed in defeating him, the game ends, and you win. CHEERS!!
