Every time I get a level up, I'm unsure if anything changes / I don't see anywhere that has info on it or anything?

I just bought it today with Deal cheaper. I'm forward it to play today but i had issue come to computer for selection map but keys to interact seem dont work and i cant click on computer but only it worked to pick up a phone after have a little chat girl and i cant click up or down to talk more. Played on Steam Deck Oled. hope need a help to fix update and i was about excited to play like Call of duty zombie clone but I'm bummer lol...

how do i do them on the ww2 map and the futrue ones?

I thought it had random generated levels becaues its very simple and do not offer anything new to me in this genre.

i need update pls
