Metal Slug Anthology on PSP (PSN) is a time capsule. It’s a deeply flawed but incredibly generous collection of some of the finest 2D action games ever made. The PSN digital version fixes the worst of the UMD loading issues, but it cannot fix the cramped controls, lack of online play, or the unforgiving arcade continues.

Seven of the most chaotic, beautifully animated, and notoriously difficult arcade run-and-gun games in history, crammed onto a single Universal Media Disc (or digital download). For fans of 2D action, Metal Slug Anthology sounds like a dream. But how does this explosive package hold up on the small screen of the PSP, especially in its digital PSN form?

Installing the game to a PSP’s Memory Stick (or playing on Vita/PS3 via PSN) drastically cuts load times to a more reasonable 5-8 seconds. It’s not instantaneous like the Neo Geo originals, but it’s absolutely playable. If you have a choice, avoid the UMD and buy the PSN version.

An explosive, frustrating, gorgeous, and essential collection for patient fans. For everyone else, keep a stack of digital quarters handy.

If you have a PlayStation Vita or a modern console, you have better options (the ACA Neo Geo releases or the Metal Slug XX port). But if the PSP is your only retro handheld, or you want seven games for one low price, this is still a blast. Just keep a pillow nearby to punch when the final boss of Metal Slug 3 kills you with one stray bullet.
