In Free Fire, players actually have a means of changing the way things are laid out on the screen, allowing them to place buttons precisely where they want to be for the sake of convenience. This can become extremely handy for players who want to take their battle royale experience more seriously, as an optimized control layout can help them reach for certain commands much faster.
For instance, stealth players might want to keep the crouch and sneak buttons nearer to the right stick for easy access. Likewise, marksmen would want to keep the trigger button and ADS button much closer to ensure they get the jump on enemies much faster.
