Before Super Mario Bros. defined the series, Mario and Luigi worked as plumbers clearing creatures out of the sewers in Nintendo's 1983 arcade game. Atari licensed the game for its own systems, and the 5200 conversion keeps the single-screen layout of platforms and pipes, two-player simultaneous play, and the central trick of attacking enemies from below.
Enemies emerge from pipes at the top of the screen and work their way down. Bumping the platform beneath one flips it over, and then Mario or Luigi has to run over and kick it off before it recovers and comes back angrier. Shellcreepers go down with one bump, Sidesteppers need two, and Fighter Flies hop between platforms so they must be hit while landing. The POW block shakes every platform at once, flipping everything on the ground. In two-player games, the brothers share the screen and can either cooperate or get in each other's way.
Tips for Mario Bros.
Save the POW block for crowded moments when several enemies are on platforms at once.
Kick flipped enemies quickly; if they recover, they come back faster.
Time hits on Fighter Flies for the moment they land, since they can only be flipped when touching the platform.
