No one will greet you when you enter the enemy base. This is designed to give you a false sense of confidence, and entice you to walk through the hallway without fear. However, the hallway is full of surprise traps that are deadlier than any opponent you can fight. The first part of the hallway is composed of three brick walls. Some of these bricks are capable of sliding out and ramming you from the side. If struck, you will lose half of your health meter, so two hits is enough to kill you. To avoid taking more damage than necessary, always remain at the very bottom of the screen. This gives you more time to react than if you stand closer to the wall. Proceed very cautiously, walking only a step a two before pausing and checking to see if any bricks are going to slide out. If one does, stand still and wait for it to fully return to the wall.
As you make your way past the third and final brick wall, you may notice the tip of a spear, which is being held by a statue above the first doorway. This spear is not just for decoration; it can seriously harm you. Fortunately, you have to be standing in just the right place at just the right time to get hit, but it's difficult to best determine when it's safe to pass. Judge carefully as you make your way around the pit of spikes and up to the door. Once you reach the door, you're safe. Between the first door and the next, you'll find an alcove, and in that alcove are a Williams and a Roper just waiting for you. Williams will come out first, but Roper won't leave until you're a little past him. Take them both down as quickly as you can, then advance to the right. As you pass the second door, you must watch out for, not one, but two spears that strike the area around a second alcove. As you time your way across the alcove, a dark skinned Williams will appear from behind. You may not have to fight him, however, as he may get killed by the spears while making his way to you. If he survives the trip, defeat him before advancing. Once you make your way past the doors, you'll have to inch higher to avoid the spikes. As you pass a seemingly empty brick wall, a Jick will smash his way through the wall, followed very quickly by a second Jick. You must now survive a fight against both of them. While it's a relatively easy method of completing this challenge, the elbow smash technique is really the safest and most effective means of dealing with both Jicks while minimizing the risk of taking damage. Once both Jicks are defeated, you will be permitted to advance to the final section of the game.
As you make your way to the final hallway, a dark skinned Williams and a light skinned Roper will approach you to attack. An Abobo won't be far behind them, and you will have to deal with all three at the same time. There are different schools of thought as to the strategy you should use. One says to take out Williams and Roper first since they are easier to defeat than Abobo. However, as soon as you defeat either one of them, they are quickly replaced by Jeffs, so that may not help you. The other says take out Abobo first. This can be difficult since Williams and Roper will continue to attack, but when three enemies are around, one tends to stay at bay while the other two attack. Whichever tactic you choose, a Jeff will jump down from Willy's balcony and replace every defeated opponent, for a maximum of three Jeffs. Once you have defeated three opponents, Willy will come down from his balcony on the right and through the hallway doors in the back.
Willy is a serious opponent, made even more difficult by the fact that several enemies are still wandering around and fighting you when he joins in. Willy carries a machine gun around, which gives him a considerably unfair advantage. Should he decide to use it, he will fire five bullets, all of which are capable of killing you instantly if even one hits you. He will never shoot it point blank, however. He will always attempt to back up and stand outside of your range of attack before firing, so you can prevent him from shooting if you pursue him. In addition to shooting, he will also kick and attack you with the butt of his gun. Once Willy appears, he is the only opponent that matters, and no new enemies will appear. Once again, you must choose between two strategies. You can either focus entirely on Willy until he is defeated, doing your best to avoid getting attacked by any other remaining opponents. Or you can try to knock out any other surrounding enemy before dealing with Willy. If you manage to kill Willy before any other enemies are defeated, they will essentially run away from the fight.
At this time, the game is complete for a single player. Billy will rescue Marion and the credits will roll. However, if you are playing a two player game, the final fight will occur between both players. The timer will reset to 30, both players will get all of their health back, and extra lives will be removed. Then it is a competition to see which player can knock out the other, or do more damage to the other before time runs out. In rare cases, this fight may glitch, requiring one of the players to commit suicide by running off screen. Players that managed to precisely calculate their score before entering the fight can also obtain an extra life during this battle. Once one player is defeated, the other player goes on to rescue Marion and win the game.
