There was a video game I played with my babysitter's sons as a kid. Around the late 90's, maybe 2000. Had to be the PS1 as
I remember playing Vigilante 8: 2nd Offense and Spyro right afterwards.
It was a space combat game. Dark colored and sci-fi. Two opposing bases that, the longer they waited, the more vehicles and weapons they could generate. Ten seconds for a canon, 25 for a tank, 60 for a special vehicle like a 'flying fortress'. It was a maze like environment, where you could set up canons along the wall of the tunnels and maze, and around bridges to take out tanks as they came towards your base.
The first one to get their tanks inside the enemy's base won. The 'flying fortress' would just fly around and destroy canons and tanks.
I think the weapons/vehicles had an electric/fire/laser thing going on. Hard to remember.
We played it just once or twice, as it wasn't that exciting for them. But I remember winning at it and loving it.
I've tried googling a multitude of terms and keywords, but nothing. And I looked, and it's not 'Future Cop'.
Any ideas?
