Metal Slug is a visual marvel, with jaw-dropping pixel art animations that stand among the best in the genre. As a classic run-and-gun game, it offers thrilling action, but its dated controls can be a hindrance. The inability to free aim while locked in place or shoot straight down without jumping feels like missed opportunities. Additionally, its arcade nature can lead to unfair situations, with the game spamming enemies and projectiles, making dodging nearly impossible at times. The final boss is a bullet sponge, leading to repetitive and frustrating encounters. Despite these flaws, Metal Slug remains a fun experience for fans of the genre.
