The scary thing is there are speed hackers that are not maxing there speed for a minor advantage over better players. Would be nice if we could get automated silent reporting on these guys and bans after x amount of abuse. The only question is how do you detect a speed hacker server / client in udk.
THis. They are much more subtle. They can feint and block multiple times in < 1 second. Their weapons swing a bit faster, and unless you watch and play a lot, you would never notice.
