So once again Bill over Green Skeleton Gaming Guild is naming names! He's calling his wormholes umm wormgates! Great & he's also using two none Old School products both of which I actually own! You can read his awesome entry Here
These are two fine D20 products which certainly have some amazing stuff going for them!
Monte Cooke did a much more evocative space effort way back before he came out with Chaositech called Dark Space For Iron Crown Enterprises!
Much of the tech in Chaostech is found within the pages of Dark Space along with a few more Lovecraft style monsters! Also the game has a much umm Spell Jammer feel that can easily be converted over to Terminal Space!
According to the backside of the product :
Dark Space is a complete campaign setting as well as a unique combination of science fiction fantasy and horror. Contained within are detailed descriptions of twenty different worlds and the society that binds them together. Organizations, religions and governments of this fantasy/high tech society are included as well as a number of new races and beasts unique to the setting.
I need something slightly more horrifying then this though & old school?!
Great Weapons, Cults, Old School, with Gun because We always need bigger guns!
Ahhh that's better!
Much Better !
The party might be mercs called in when they investigate the appearance of anomalies (called "earthquakes in time") that allow the passage to other times and places, allowing often-dangerous creatures from the distant past or future to threaten the lives of citizens.
This approach is very reminiscent of Primeval
I 'd more inclined in my games to call these things cracks in time & space.
There's myriad of alternative worlds, time tracks, & other places to go.
I'd love to use some of the ideas that were presented in this book
Then take the Crypts & Things book then run with it!
There's a particular film I've been aching to run
