playstation demo disk game hunt

playstation demo disk game hunt FOUND " Blast Chamber "

hi im looking for a game that was first shown in a playstation demo disk

there a 4 different colored players in a 3D map with different colored spots on the walls floor and ceiling
and you blew up the colored squares before the other players

if anyone knows the demo disk or the name of the game im describing please let me know ive been
searching and wondering about this game for almost 20 years

 

Was it PlayStation underground or a 3rd party disc?

 

it came bundled with the playstation so it was an official demo disk it was back at the very beginning of the playstation release

 

Is this the game you're looking for?

 

BINGO thank you so much

 

I had a feeling the game you was talking about was Blast Chamber because Blast Chamber is at far as I'm aware the only PS1 game that had 4 different colored players in a 3D map with different colored spots on the walls floor and ceiling with the goal being to blow up the colored squares before the other players, glad I was able to help.
