Vanguard is basically an exact copy of mw2019 but now it has manditory end of game cutscenes that take forever, not as many crazy skins (for now at least), tons of glitches that are super noticable, and the field upgrades and perks are a little different, slight improvement imo and dead silence is back. Don't be expecting some great ww2 experience that's like historically accurate and all that. If you're trying to buy one I'll just say that after an update several months ago I'm totally unable to find a single match. I mean like 40 minutes will pass and no match. I checked reddit and apparently they put some bug in the game where certain maps won't load for some people unless you're me and the whole thing is messed up. You might have better luck than me after fixing it idk. Tons of other people had the same problem so you're a bit late for mw2019
