The game offers four levels of intensive classic shoot em up gameplay and is one of the few back then that didn't try to copy Katakis, Armalyte or R-Type, except that when holding the fire button, an increased power shot is released. Each level has its own level design and you must fly through several landscapes avoiding crashing on fore-ground obstacles while shooting enemy hordes. Enemies vary from huge alien ships to laser-turrets and ground troops. Destroyed enemies occasionally leave behind power-ups that can be collected and increase firepower too. There is no energy bar, so a single hit will take you down and start at a certain point of the level. Extra life can be gained by reaching 50.000 points too. At the end of each level, there is a huge boss waiting for you too.
Lethal Zone is a quite addictive shooter, it has its own style and is quite playable without being too hard or too easy. Loads of aliens, loads of weapons, mean levels ass up to one immensely satisfying game. Unfortunately is sort, and only 4 levels are available.
Graphics are nice, offering detailed enough backdrops, which differentiate to each level. There are no special graphics FX here such as multi parallax scrolling, but everything look and move quite good. Sprites are nicely designed and move pretty fast on screen too.
Sound-wise it's top notch though and it does its purpose well. Each level offers a unique tune whilst are several high quality SFX including awesome explosion sounds, laser firing etc. The introductory tune is among the best I ever heard on an Amiga game.
