I will love you all forever if you can help me out.Im looking for a rpg, I only had the demo for,I think it was in a jump pack.It was in some post apocalyptic world I think.There were three characters,and one of the was a robot dog whose whole head turned into a cannon.I remember running out of a city fighting more robots or something,then you head into a desert towards some factory or something.Oh,there was this really long bridge I think.That might have been in the desert.

@roninjaz: I looked around for a while and couldn't find it, I searched through this PS1 RPG listand this post-apocaliptic game list (maybe one of the names will stick out to you or I missed something) but couldn't find it sorry. Of course you could do it the old-fashioned way and look through all of them at the bottom of this page.

One thing I learned: Holy SHIT there's ALOT of PS1 games with dragons in them. Good luck in your search and Welcome to Giant Bomb :)
