Play Metal Slug 2 online free – Eri and Fio join Marco and Tarma, plus aliens, mummies and new vehicles. No download, 2 player online co-op.
Metal Slug 2 (1998) expanded everything the first game started. Two new heroes, Eri Kasamoto and Fio Germi, join Marco and Tarma, and the war against General Morden takes a strange turn: deep in the deserts and cities you meet mummies, aliens from Mars and more of the series' trademark weirdness.
New vehicles appear – including the Camel Slug and the Slug Flyer – and new transformations, like turning into a mummy when you are hit by a mummy's curse, or getting fat when you eat too much food (which makes your shots bigger but your movement slower).
The classic H, R, F and S weapons return, joined by the L – Laser, a beam that cuts through rows of enemies.
Metal Slug 2 is famous for slowing down when the screen gets busy. Some players love it – it gives you time to react – but if you want the smoother version, play its remix, Metal Slug X.
Next: Metal Slug X. See all games on the Metal Slug hub or in Metal Slug games in order.
Tip: a gamepad makes special moves and long combos much easier than the keyboard.
