Isin-Densin Zero is yet another excellent vertical shooter from Japan's rapidly growing freeware scene. You know the drill by now: excellent graphics, smooth gameplay, and a lot of cool ship designs. The game goes above and beyond most other freeware shooters in the "extras" department. The soundtrack in this game is excellent and fits very well with the frantic action. Weapon sound effects are similarly outstanding, and effects of power-ups are beautiful. The game is also much longer than an average freeware shooter, spanning over 6 levels, each with its own background graphics. If you like vertical shooters, Isin-Densin Zero is a great underdog that you should definitely take a look at. Thumbs up!Reviewed by: Underdogs
