I had light bulbs (They could easily be downloaded from figona forums ) and changed textures in the past.
Never had wallhacks (that I used online, tested some of them in my own private server)
Never had snipermask
Never had auto-aim / auto-shot things
Now I only use 3 screens to observe the enemies and play at the same time, a nice radar where the enemies are visible and I sometimes call in artillery when I'm angry.
