The ending also has some extra images rather than the stark black of the original Metal Slug 2. Plus, there are enhanced versions of all of the regular weapons – if you wield these when in “big” mode, they look different and are even more powerful.
There are plenty of new enemies, including mummy dogs in the pyramid levels, and new weapons, like the awesome Iron Lizard, which sends exploding mechanical devices flying along the floor, the bouncing Drop Shot, and the homing Enemy Chase. The first stage boss has been changed to a midboss later in the game, and has been replaced by one of the bosses from the original Metal Slug. There are more enemies and weapons in general, making for a much more havoc filled experience, plus power-ups and weapons are more prevalent.
The music is basically identical, although like the visuals, some themes have been remixed and enhanced.
Although the levels are the same, many of the stage graphics have changed so you’re fighting through areas at different times of day – you fight in the first stage under the cover of night, instead of during the bright sunlight of day, for example.
