How to parse udp packet?

Question

Wireshark

It suddenly became interesting to me how the game client and server communicate with each other and what kind of data they transmit.
I have zero knowledge in this matter, I just heard about the wireshark program, downloaded it, filtered it, found the tcp packets of the game I needed, opening the tcp stream window, all data is readable, transmitted in xml format. But the main part of the data is transmitted via udp, and here everything is very unclear to me, opening the udp stream, I see only unreadable gibberish,
you look like this:

...j.$\.....0.........93...k....|.+K...].H.L
.3...wJ..+...a.n...Q.H...0V...k........r.B...
_......P;.....n.......$..,/>....k......>3W..y6\0.b.-:..7...GD....[I.>..IQ.9.....k....l...j7.t.;.-(......!..L....sc...c......$...k.....~{+.E ..........."c)*(|&...N....,#..p&....k.........B.C....T.j0...'..h.L....k^Y,.o...L....k.......5..c2..;...;D...*=...Y...q...

I skimmed through and couldn't find any readable words.
So is this just encryption or am I an asshole?
I doubt it is important, but still, the game is wot blitz

Answer 1

The lbmz header indicates that the data is compressed by some kind of zip algorithm. Try saving as a file and opening with an archiver.
