Manesis '99 Kai

Manesis '99 Kai is a Gradius fangame, featuring seven stages and many mechanics used in older Gradius games.

Overview
Manesis 99 is very similar to GR3, in that they are both fangames made to appear like MSX games. However, Manesis is more like an MSX game, due to it having music which an MSX could generate, while GR3 does not. Manesis is very inspired by Gradius games that were recent at the time (e.g. Gradius Gaiden, Gradius IV) and is generally considered one of the better Gradius fan games.
