Here's some solid ports of early Marvel games and i am happy to relive some of the joy and suffering from my youth. Features include the now obligatory save states and rewind button as well as multiple platform versions of applicable titles. Happily there are cheats available for some of the games, which vary in usefulness: for instance, Silver Surfer has Unlimited Health, Bombs and Lives which trivializes that beast, while Arcade's Revenge has Unlimited Lives; helpful sure, but you're still going to know the relentless agony beating that game provides. Sweetly, for those who chose not to beat the Silver beast with cheats, there is a turbo fire button which is pretty much required.
A few greats are here: X-men Arcade, Captain America and the Avengers as well as Silver Surfer (most would disagree on this game being good BUT: my house, my rules). Also included are some truly mediocre titles: Maximum Carnage and its sister game, Separation Anxiety as well as that ravening nightmare of a game, Spiderman and the X-Men: Arcade's Revenge.
There's also a bunch of fun stuff like a music player, a handful of design documents, instruction booklets etc.
I lament that Spiderman vs. the Kingpin as well as X-Men for the Genesis weren't nestled in with these games of yore, but am still very much enjoying what's here.
I have seen comments regarding some trouble with internet play as well as achievements. The latter works fine for me, and i cannot comment on the former, as i have no interest in playing these titles online.
Thus, this collection gets a thumbs up from me!

Good old-fashioned Gen X side-scrolling beat 'em up. Torturous difficulty at its finest. My review is primarily on the X-Men game since that's the centerpiece. I appreciate the attention to detail and the fact that it's like playing on an arcade cabinet. Mostly responsive controls if not surrounded by enemies on all sides. "You are dead, X-Chicken."

A fine archive title for when you have that nostalgic itch with a few caveats. I wish they had not just re-released the original title but made some subtle tweaks to the experience.

Updated Voice acting lines and tweaked the enemies in general. Would have made the game even more fantastic; they missed it.

As for difficulty, it's a button-mashing quarter guzzling, tear drinker.
You have enemies that slide up behind you to attack you from both sides, enemies that club you (rifle guys and lizard guys), which you can't defend, ranged enemies that shoot you and seem to read your controls to dodge, and bosses that ignore your attacks and club you to death. Makes it a very cheap quarter hog.

They could have added in free power use instead of requiring your health, as when you're swarmed by a screen of cheap enemies, you have to use your power to avoid dying. I played it on difficulty 11, hoping that they included some sort of real ending, but nope, it's just loops forever. For what it is, gonna give it a C+. Could have been given some love and made into an A. If you miss playing it, don't miss getting it. Experience a beat 'em up in true Gen X fashion, that offers no apologies and cheats with its soul.

While this game is brutally punishing I still enjoy it to an extent due to the nostalgia factor. HOWEVER, my friend and I beat Separation Anxiety from start to finish and the achievement never popped for beating the game Cooperatively. SOOO hopefully they fix that and I'll be less bothered about this collection. But yeah either way this game is difficult so don't expect it to hold your hand like all the other modern games out there do.
