It’s like contra but crazier and more stupid.

This was my first exposure to the series and this was certainly a great one! Insane with the difficultly and level design. It’s a very chaotic game to play hardly any down time to be had but still super fun. The awesome weapons and controls helped this game feel fair dispite being super difficult. Really solid campaign I really enjoyed all the levels. The graphics are really great with a charming art style and signature SNK detail.

The Ps1 version also have infitne continues so if your bad at run n guns like me have at it! I didn’t even expect to beat this game. Just picked it up expecting to lose all continues by level 2, little did I know I had unlimited tries.

I competed the game as Fio with 61 continues used (imagine how many quarters lol) I would like to give the game another go and see if I can get through with less continues....hopefully.

Cartoon ultra-violence? What a great way to spend your lunch break!

When I worked for EA as a tester, I got to eat lunch in their fancy cafeteria. When I wasn't hanging out with the colleague that was a fruitarian or freegan or whatever it was, I would play Metal Slug X on the NeoGeo arcade machine while everyone else played Tekken. It's a bit of a bullet hell side scroller, but with a silly amount of secrets, vehicles, and weapons. The whole Metal Slug series is like that and I'm sure that the folks who programmed them had a blast coming up with ridiculous things to do as weapons, enemies, sounds, and ways to die. The graphics are a bit cheesy for the year this came out, but you're not playing this for graphics, you're playing because it is ridiculous.

It definitely is ridiculous!

Review from thedonproject.com

Kids these days they don't know about how it was in the 'cade. I used to shove old Billy "Measles" Harwood around in the mall bathroom stalls until he'd fork up the money his mom gave him to buy insulin. Then I'd get a Surge down at the corner with Wick'd Johnny and exchange to quarters. I roughed up lil Billy every other Thursday for about 4 years until he ran in front of a Ford Contour. Poor old bastard. Anyway I still didn't make it past the third boss. I totally got roflcoptered by that Metal Slug. Lost my virginity on this very cabinet though. Awesome.

"Metal Slug X" is one badass game! Building upon the first game and adding a whole new level of scoring, power ups and character switching in game. This all amounts to my second favorite game in the series. The character designs, the in-jokes, the charmingly outdated but creative movie references and just the manic nature of it all speaks to my soul. This is an updated version of Metal Slug 2, which fixes the severe slowdown of the original release. However, there is still a little noticable slowdown from time to time, but not enough to care or even knock the game for it. I love this game! Like many of my favorite Neo Geo releases, it never gets old.

Now THIS is how you do a sequel. While I'm not entirely sure what happened with Metal Slug 2's development, I appreciated that the developers decided to remake it with a new engine they built for Metal Slug 3, and that's how you got Metal Slug X!

Compared to the original version, Metal Slug X has new enemy types, new weapon types, more dynamic confrontations with remixed enemy/weapon/vehicle spawns, and--most importantly--much more responsive gameplay that doesn't slow down nearly as much.

All-in-all, this is the most defining game in the Metal Slug series, but of course it wouldn't be until the next game that we'd receive run-n-gun arcade perfection . . .
