3.5/5 ★ – Visionary_Gamer's review of Metal Slug 4.

I could probably start copy and pasting my previous Metal Slug reviews here, but Metal Slug 4 brings more of that fantastic pixel art, chaotic gameplay and immense fun. I was hoping MS4 would improve on MS3’s wackiness, but it remains quite tame throughout, for Metal Slug standards anyway. And it is a little shorter than previous iterations. The final boss was a lengthy, epic and memorable process. I’m just too bad to find these games as enjoyable as others seem to. But despite using countless “continues”, I enjoy them regardless.
