How do I convince my girlfriend to play cod zombies with me again...

So we're watching squid game the other night and she's like all amped up suddenly like "I wanna play a shooter game I wanna shoot something" (don't take this out of context lmao)

Naturally, I saw this as my golden opportunity to finally play a fun couch co op game and she finslly agreed to play COD zombies with me, so I chose Black Ops 2 Buried

Buried, I thought was an easy map, until I realized it's not a map to play if you've never touched call of duty before

So in hindsight... TERRIBLE CHOICE

Within minutes she was like "WHATS HAPPENING" and probably gave her too many instructions like "oh yeah you gotta leave a crawler after every round so I can do the steps", "don't shoot the big guy his name is Leroy he's friendly" "it's not safe to knife after round 2" "Whatever you do... don't buy the Olympia"

She told me it was too overwhelming and noped out fast... so now I'm waiting till my birthday (which she will then agree to play cod zombies again JUST for my birthday)

what map should she play? (I have bo1,bo2,bo3 and all DLCs)

And ideally a less chaotic one, so I can sign her up to our cod zombies cult ONE OF US ONE OF US cough I mean make her become a cod zombies fan
