    OllyDbg

    Can anyone tell me if there is any way to open Engine.exe in OllyDbg while the game is running?

    Get parameters from the launcher using a program which can display startup parameters.
    Open Engine.exe in Olly (dont attach, open a new process) and change the startup parameters.
    Restart the process and manually bypass HackShield and Blackcypher (nop init call + jump the jne/jnz and mov al,1 + retn for BC).
    Now you can run the game for 2 minutes with all debugger functions
    Have fun.

    Progress with my game - "Disbanded"
    • Fixed FPS lag on spawning entities due to the ent_preload buffer!
    • Edit the AI code to get some better pathfinding
    • Fixed the view bug within the sniper scope view. The mirror entity is invisible now!
    • Added a new silencer for ALL weapons. Also fixed the rotation bugs
    • Added a ton of new weapons and the choice to choose a silencer for every weapon
    • Created a simple AntiCheat, noobs will cry like hell xD
    • The name will be Disbanded, the alpha starts on the 18th august 2014



    Some new physics fun (Serversided, works on every client)

    Thank you! But opening Engine.exe by OllyDbg I can not find any string and no intermodular calls!

    2 minutes because hackshield has a heartbeat and will DC you automaticly.
    To find strings you have to run it to a certain point becuase the file was packed with winlicense/themida.
    Just run it and pause after its unpacked.

    Nice, from what I understand I will make the combat arms start without anti-hack, so I just put mov al, 1 in HS and BC initialization but gives crash on the login screen. I did something wrong?

    Maybe they added more protections to it, make sure ehsvc and blackcipher modules are never even loaded.
    If the crash is done by game you might even hook the API's like ExitProcess etc. to stopthe game from doing that or to find returnaddress and patch it manually.

    Download: http://ch4ozz-c0d3r.de/Game/
    Keep in mind its pre alpha and I dont have any servers open yet. Port is 1001 if you want to open one (UD and TCP)

    Yes, has a check at login. I think that is related to this address:
