Why is Metal Slug 3 considered the best?
Metal Slug 3 has the most content of the classic games - branching routes in each mission, new vehicles, transformations and an epic final mission - while keeping the hand-drawn style at its peak.

Play Metal Slug 3 online free – branching paths, zombies, giant crabs and a final mission to space. The biggest Metal Slug, with 2 player online co-op.
Metal Slug 3 (2000) is the most ambitious game of the classic era and the one most fans call the peak of the series. Marco, Tarma, Eri and Fio return for five missions packed with ideas. Almost every mission branches into different routes – underwater, in caves, on mountain cliffs – so no two runs have to be the same.
The enemies are wilder than ever: zombies that can turn you into a zombie (with a deadly blood-vomit attack), giant crabs, man-eating plants, yetis and, finally, the alien Mars People in a final mission that takes you all the way into space.
New vehicles include the Elephant Slug, the Ostrich Slug, the Drill Slug and the Slug Mariner submarine. Transformations from earlier games return, joined by the zombie form – slow, but with a screen-filling special.
Metal Slug 3 has the most variety, the biggest bosses and the most secrets of any game in the series. It is long and challenging, and the final mission is one of the most memorable endings in arcade history.
