I found the password for his archive and I used that password to open it with Freearc. Freearc is showing exactly the method he used (like me srep+lolz). And as confirmation I have installed his repack monitoring the installation from the task manager and XTool is not running, only srep and lolz:



However I tried what you suggested with the plugin "unrealengine_R13"":

XTool v0.8.9 here, only testing the decryption part and it stucks at some point:



I tried also adding zlib+reflate after the key and it finds many more streams but stucks at the same point and anyway as you can see the size is not increasing, maybe the streams found are very small:



this is with XTool v0.7.9, it doesn't stuck but it finds only 13 streams and I don't think this decryption can give some benefit:



I guess the plugin "unrealengine_R13" is not compatible with these pak files format. I tried also extracting them with quickbms and "unreal_tournament_4_0.4.27e_paks_only.bms" but it is not able to decompress all the files...
