Salamencetrainer34, It's uh. basically Star Fox but with laser-spitting dragons and a higher difficulty.
The plot boils down to this: Some time in the future humanity colonized another planet (probably Mars), set up Towers to terraform the land, and went into cryogenic sleep to wait for that process to finish.
Except it never did and the cryogenics failed, so all those people are dead and all the straggling commoners are just kinda left on this half-hospitable planet with malfunctioning Towers that keep spewing out monsters that I think were originally meant to protect the Towers. Somewhere along the lines a program with unknown origins called the Heresy Program infects and mutates a baby lizard thing, turning it into a dragon, which needs a rider to carry out its mission properly, which is to destroy the Towers.
Or something like that :V You probably haven't heard of it because the first three games in the series were for the Sega Saturn, a console doomed from the start. The fourth, Orta, came out on the XBox but since most people hadn't played the originals, it went by rather unnoticed.
