I've tried three of the four programs for Warzone on here. The only one I haven't tried is Leviathan. I'm just curious which one do you guys believe to be the better of the four? I've personally noticed some are more accurate and have better features than others. So far Premium is my favorite, but I'm wanting to give Leviathan a go. Whats everyone's opinion? I've yet to find something that provides me with crisp smooth sniper shots like another program I once used, but no longer is available. Maybe I just need to tweak and experiment with settings, but honestly there's no guide I can find that suggests different settings. I'm using controller through an app and using the right trigger as my hot key is good, but when people are watching me I have no way to deactivate it. So any advice is more than welcomed!
