One of the games is Mission Against Terror Online and uses the "KFXArchive" magic.
In another game the data was simply xored with 0x9d but this is not the case apparently and it doesn't seem a one-byte key like that. No idea.

What's the name of the other game?
I'm not sure if it's obfuscated because the headers in it are readable, maybe it's just unsupported.

Please next time open a separate topic for each game and specify the full names of the games.

Sorry, my mistake, Game 2 is MAT, and Game 1 is Metro Conflict, which is supported but idk why can't open by umodel. Seem like gildor just take a look of Metro Conflict version Korea, so umodel didn't work with other version of that game. My sample files are from US version, because MC Korea is terminated.

Maybe try to contact Gildor just to ask why it doesn't work.
