Armour-Geddon.
It's a strange game where you macromanage a base and build bombers/fighters/tanks/hovercrafts in an alien planet, trying to get materials to build more and assemble parts of a neutron bomb or something. These are a combination of real world tech (the vehicle bodies are pretty much 21th century stuff), but you can put a laser as a "anti-light armor" weapon, and arm your tanks with tank shells and stuff. They handle pretty interestingly, specially the hovercraft which is a real-life version with skirts and all. And a bitch to maneuver.
You also could drop teleporters with your bomber, but I think could drop only 4 or so and they were indestructible, because the map is huge. They work more as "checkpoints" for land vehicles. Oh and don't ever expect your bomber to come back, you're pretty much going to wait till the last second you have to live to drop the telly as far away as possible
Anyway I thought the game was frustratingly hard. There is a time limit and you can run out of minerals. You can pick up more minerals with your tank I think and your base mines them very slowly. Even though I never made much progress I think it was a fun time sinker, heh.
But there you go.
I used to play the Amiga version, on an actual Amiga. I think there's a DOS version too.
