Challenge games

It was on easy, and with luck, I got a celestial ion cannon quickly afterwards, both near the start of the game. I've been trying to replicate that win, without success.

An easier version of this challenge is to disallow upgrades on anything you built yourself. These challenges unfortunately forbid fighter bays, as they don't drop from anything. Light guns are similarly difficult to fully outfit a ship with, as they drop more rarely than heavy guns.
