This is one of my favourite PC games of all time.
It's pretty much a forgotten gem, which is a great shame. It is a unique game that manages to combine strategy with blowing chunks of metal out of people. It's possible to manually control everything, manually gather resources (like a strategy game), manually shoot at people who would shoot at you (like a dumb tank shooter). Alternatively, you could leave it to the AI and plan your attacks out, just like a strategy game.
This game therefore turns the strategy genre on its head, allowing you to have more direct control over your units. You can have the AI do all the boring stuff, taking land vehicles from the carrier deck to the actual land and then go looking for resources, while you take control of the aircraft taking people out.
As the game goes on, you get cool upgrades, new weapons, armour, different units, all kinds of stuff. You get more AI characters to control your ever growing army, and you'll end up with some intense battles against the hordes of... well, hell if I know. The story is a bit weird. The gameplay is where it's at.
I haven't played a game like this. It's a shame really, this game is really innovative and I would have enjoyed a sequel. Unfortunately, the developers went out of business. Kind of a shame, they started off in my birthplace.
You won't regret buying this game if you like explosions or strategy. Oh, a small bonus since you read this far: hold down the right mouse button when you are in the Antaeus construction room and move your mouse. Ahh, I love random attention to detail!
