King Of The Monsters was released on NEOGEO back in 1991 by SNK, and has been ported directly to the Xbox One by our new best friends over at the bizarrely named Hamster Corporation. A mixture of fighting and wrestling, you choose one of six monsters and battle in cities until one of you pins the other for a three count, earning bonus points for destruction of the landscape. This is one of the trickier ports so far, needing a fair bit of practice to get a few of the achievements. You only need to play each game mode once, but depending on luck and how fast you get used to the controls, may take few more tries.
Step 1 - Original Mode
Start up in original mode. You can change the settings to make things easier for yourself by pressing and changing the difficulty to 1. Your score will not carry over if you continue, and you only have one life, so you will likely have to practice a bit to get all of the achievements. You can use the save states so you can retry if you get beaten, see the guide for how to do this. Play until you have all of the point achievements. Once you have them, let yourself get beat and unlock the two high score achievements if you don't have them yet. 5 achievements for 420.
Step 2 - Hi-Score Mode
In Hi-Score Mode, you have to test yourself against the computer at level 4 difficulty. There are no easy solutions for this, you just need to get good at the game. All the characters are as strong as the others, so pick whichever character you like. Once you have the score related achievements, let yourself get beat and upload your score for the related achievement. 4 achievements for 340.
Step 3 - Caravan Mode
Rinse and repeat what you did in step 2, this time in Caravan mode. As well as not being able to change the difficulty, you have only 5 minutes to get the high scores. Try to cause as much destruction as you can in the first fight, this should set you up to beat the second guy fast, giving you the full points needed. Once you have the score related achievements, you can simply quit out. 3 achievements for 240.
This is one of the tougher ports so far, twinned with the fact it just isn't a very good game. Most of the achievements are easily within reach, but the last few may take a few hours of practice if you can stomach it.
