If you play the game normally like losing a round or did not finish the opponent with Super until after the final boss, no matter how good you are, you'll still get a bad ending after you defeat Serious Mr.
Fighting the true final bosses requires a lot of conditions, some are incredibly stupid like defeating opponents by dealing chip damage until they die. Controls aren't as good as other SNK games. Some moves are ridiculously hard to pull off. The CPU, specially the final bosses are ridiculously cheap. Having Goenitz as a mid-boss (specifically as the default mid-boss) is a terrible idea, since he is known for being an extremely cheap character with his spamming of ЁНОКАЗЭ/Yonokaze (tornado move). One third of the characters are locked behind a cheat code!. The AI in the game is extremely cheap and will block everything, even on the easiest difficulty, making it an absolute chore to defeat them. Many characters are extremely broken, most notably Geese Howard and Zero. In terms of character balance, the game is an absolute mess. Also for some reason the dodge takes away from your meter, unlike previous games where it was completely free. For some reason you cannot run in this game despite being a notorious mechanic of SNK games, instead you can only dash. While many of Capcom's characters look pretty good redesigned in the KoF style, some of them look absolutely terrible (a notable example being Sagat). A majority of people are either missing or dead, only 36 of them survived, but now locked in a war between Chaos and Order to decice the fate of the universe, whoever wins the war will make them return back to thair peaceful century. The game takes place in a post-apocalyptic future where civilization is scarce and desolate.
