How to Play Back to the Future Part III
Quick start
The game changes rules across four short stages. In the opening horse chase, react in sequence: jump over crates and gaps, shoot axes and birds, duck under rocks and riders, and hit clock icons for extra time while closing on Clara’s buckboard. In the shooting gallery, change the gun’s height instead of firing only at the nearest ducks; high-value gunmen, pigeons, and background bandits are needed to reach the score target. In the street showdown, move the aim between windows and rooftops, throw plates, and return to the table when ammunition runs out. On the final train run, keep moving, jump gaps, defeat knife throwers, and collect the coloured fuel items before the timer expires.
