The upcoming new version* of Universal Anti Cheat will likely not detect SWAT 4 .ini modifications just like its predecessor UAC 3. Editing .inis to gain an unfair advantage is achievable in v1.0, although it is blocked in 1.1, which was one of the main reasons the current BS tourney is being played over there.
*Upcoming could still mean many months, as a large amount of time has already surpassed since developer DeXuS said UAC 4 was 90% ready.
