C-4 - about the game
Elevate your skills in any favorite game through nonstop training with C-4. This indie action tool runs seamlessly on top of games set to Full Screen Windowed mode, letting you practice without switching applications. Press Esc to minimize it anytime, keeping your focus sharp. Launch C-4 first, then start your game and tweak settings like enabling Play Audio When Game In Background via the developer console with snd_mute_losefocus 0. Set engine_no_focus_sleep 0 to raise the background FPS limit. It leaves performance untouched, records nothing, and avoids altering game files, perfect for casual players honing edges over rivals.

Do you want to be the best in your favorite game? Never stop training!
