Before Empires League officially began its first season we tried out all of the publically available hacks we could find on empires (CSS ones, etc). Most only partially worked. The ones that did work only allowed wallhacking. Automatic headshots didnt work and nothing at all worked when tanks were concerned. Wallhacks are kind of moot since engineers can place cameras and commanders can highlight enemies.
VALVe DID release the HL2 source code, you get it by using "create a mod" in the Source SDK and using singleplayer code. Also, somebody used an exploit in outlook to slowly leak the hl2 beta contents so he could get it.
I can think of three unique methods to get a wall hack in Empires, one of them is effectively unstoppable. The key is that most people can't think of one method, so you don't see many.
Who are you talking about? What are you talking about? I think this thread has gotten totally derailed...
No binaries, no dodgy bits of software just walls you can see through. It's a problem that's now been fixed in CS:S but afaik that's the only one.
