wow if you like gradius, salamander, parodious or any of the many other shooter konami makes get this game. great compilation. Infinite fun!

Each game a classic
An excellent collection of games that will test you to the extreme!

Longtime gamers will be familiar with Gradius 1&2 (or Nemesis as it was called in the West), but the inclusion fo the rarer Gradius Gaiden is a welcome one.

Also, Konami have made a good effort with the presentation as well - with an additional video and soundtrack gallery included in the game.

Graphics and sound quality is much superior to any emulated equivalents - so it's worth a look.

Gradius Portable Collection
While playing a few of the games takes some getting used to because of the position and sensitivity of the PSP directional pad, this is by far the best investment in a PSP game for any arcade shooter fan. Combines the best of console, arcade, and portable gaming. This game alone is worth having a PSP!
