Rockstar has explained how character switching between Jason and Lucia will work in GTA 6. Rob Nelson, Rockstar North’s co-studio head, says switching won’t always be available, some missions lock you to one character, some force a switch, and others let you freely alternate between Jason and Lucia. This is for story progression and to make situations feel natural. Nelson cited an early high-rise mission where free switching was originally allowed. The team later locked players to Jason because his ex-special-forces background made him a more natural leader for the situation. Other missions require switching as part of gameplay, in the trailer’s bank robbery, you first control Jason while Lucia drives. Later you switch to Lucia and drive while Jason and Raul keep shooting at police. Some missions also allow free switching between Jason and Lucia, including the attack sequence at the end of the trailer.
