How to unlock the Cleared: Metal Slug X achievement in METAL SLUG ANTHOLOGY - Definitive Guide
All you have to do to get this trophy is finish the game in general. It does not have any difficulty/continue restrictions attached to it, so I'd suggest using EASY/FREE PLAY settings. After you defeat the final boss, the trophy will pop!
