I don't know why they'd want to even re-do MW4, unless it was to have to not need such huge downloads for the additional mech designs they came out with in the 3 packs...
I played all of the MW4 series, Vengence, Black Night and Mercenaries, still have them, but Mercs was my fav for all the mechs MeKtek added. It just rocked...
Played all the Co-Op missions several times with a few of the XC gang, it was a blast.
Now, if they had a game with ALL those Mods, and ALL the other used made maps that were just so awesome, there was probably 40-50 I downloaded, many more that I didn't...
packed into a couple DVDs, THAT would be cool...
The engine was smooth in Multi-player, well, most of the time, there was still the connection factor.
MW really needed High-speed to play smooth like most higher graphic games...
I really liked MW4 over MW3 and MW2...
Sad to see MS just wash their hands of it after only a cple years, although MekTek did a good job of keeping the game alive...
