Metal Slug X was released on NEOGEO back in 1999 by SNK, and has been ported directly to the Xbox One by our new best friends over at the bizarrely named Hamster Corporation. Metal Slug X was SNK’s remake of Metal Slug 2, with more polish and an increased difficulty. Along with most of the other games so far released in the ACA series, this side scrolling shmup is a pretty fast completion, requiring little real skill to finish. You only need to play each game mode once, but will most likely may take few more tries.
Step 1 - Original Mode
Start up in original mode, and change the difficulty to 1 and change players as high as you feel you may need (go into the options menu with ). Run through the levels, killing everything you see and rescuing as many POWs as you can (you have to shoot them free then touch them with your guy to rescue them), picking up the score related achievements on the way. I you manage to perfect the first and second levels you will be most of the way there, but if you don’t, 99 lives should be plenty to get to 2 million. Once you have the score achievements, let yourself run out of lives and unlock the two high score achievements. 5 achievements for 420.
Step 2 - Hi-Score Mode
Hi-score mode is tougher, as you have to play on difficulty level 4, and only have three lives. You get major bonuses for rescuing all of the POWs, and for finishing levels in vehicles. Finishing the first two levels like this will see you at just under 1.5 million, so you will just need to blast through the third level to get this. 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 3, 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. However, this should be plenty of time in this game - all you need to do is finish the first level with all POWs. Once you have the score related achievements, you can simply quit out. 3 achievements for 240
The Metal Slug games are classics, and are just as fun to play as they always were. If you want the completion fast, it doesn't take long to learn the first couple of levels. If you don't mind the price point for not much bang for your buck, and appreciate an easy 1000, then this game comes highly recommended.
