I'd been doing *so well*, in fact I'm pretty sure I got farther than I ever did back in the day, not counting cheats.
But here in the final campaign, I was expected to fight fellow Protoss. With a sizeable starting fund, but still. My "basic" tactic of mass scouts wasn't working against their highly-upgraded scouts, and numerous
dreadnoughts dragoons. But I held back and adjusted! I formed an additional line of turrets, to delay, and built a decent force of dragoons+zealots to counter. Two waves of reapers (artillery) approached my line, but I managed to take them out with my air force... losing some scouts in the process, but still.
Then an unexpected mass of heavily-upgraded scouts beelined my defences, decimating my air force. It was a tough battle, but I had somewhat planned for this- my turrets and dragoons won the day. I utilized my shield batteries and counterattacked with a mass of fresh zealots with air support, looking to at least take out their turrets, and thus open the way for tactical strikes.
Triple psi-storm took out my entire force in a pair of seconds.
You know... Previous level (fixed amount of troops, lots of "gotcha" corridors) was BS. And so is this.
Rage-quit for now.
Starcraft, Protoss campaign.
Edit: Oh also I was attacked by a single carrier, but it hardly counts. My scouts knocked it out fast (my turrets did little, of course, since a large part of starcraft's gameplay is that your units are stupid).
I'm not even sure the enemy had the ability to build new carriers. Maybe not, considering I *definitely* didn't... Then again, likely so.
