Homeworld 1. I remember there was one battle, where I had to destroy an enemy target, some force generator - don't know exactly 10 years since I played it - you had to use the stealth kit to get near it and destroy it. It was covered with laser/beam ships. For the love of god, every time I got near it, hundreds of these buggers would chase and obliterate me !!
So, I used scouts to tease one or two of them out of that region, then I would use salvager ships to capture them. Took me days on and off to capture the lot and destroy the target. It was one of the most satisfying piece of gaming I'd ever done.
Needless to say, having a fleet of these beam ships on my side made the game a whole lot easier.
