Item description:

First off, I'm not going to take credit for this save file but I can't give credit to anyone either as I can't for the life of me remember where I downloaded the file from (was about 6 months ago and it wasn't NGU; I think I just googled 'MvC 3 save file'). I happened across a few of the threads here asking for MvC3 trophy saves, all of which ended in discussions about broken links, so I thought I'd post the save I have in case anyone is still looking for some help.

With this save I managed to get the following trophies to pop:

I Buy the Issues and Waiting for the Trade - just completed arcade mode on very easy difficulty; did it without using continues to get Saving My Quarters.

World Warrior, Champion Edition Hero and Super Turbo Brawler popped automatically after a couple of minutes of playing an Arcade match.

Most of the following popped a few seconds after completing the requirement; some popped after exiting to the lobby:

Be Gone! - performed one 'Snapback'
Excelsior! - performed one Team Aerial Combos
Big Bang Theory - performed one Hyper Combo Finishes
One Step Ahead - got one First Attack
Steel Battalion - performed one block

There are other trophies which I think might pop just by doing one action or maybe a few more to reach the required number, but I haven't got them yet so I'm not sure:

Mega Buster - I've used a few Hyper Combo Gauge bars and it hasn't popped yet, so maybe a few more should do it
Ultimate Nullifier - perform some Advancing Guards
Back at 'Cha! - perform some Crossover Counter
Galactic Smasher - perform some Combination Finishes

If anyone is able to get these trophies to pop, let me know how many actions it took to reach the target and I'll update the instructions

I haven't yet played online or Mission mode so I can't speak for any of those trophies. Again, let me know if you have any luck in getting them with this save.
