If you're into old school shoot-em-up sidescrollers, it's hard to beat the Metal Slug series. One can only imagine the insane amount of time and devotion that SNK put into making these 16-bit wonders back when they were headlining titles for the Neo-Geo brand. They were near instant cult classics in Japan, and when they found a new home on the original Play Station console, saw even greater worldwide acclaim.
When the first Metal Slug came to Android, we were quite excited. Metal Slug 3 was then released, and now Metal Slug 2 is out, completing the first three titles in the explosive franchise.
