The Clipper can quite easily solo CZs if you’re smart about it. First thing you’ll wanna do is get your Powerplant beefed up for power output, because engineering things in specific ways can add a lot of power drain and you’ll want that extra capacity. Clippers are also extremely fast and agile for a large ship, so take advantage of that and go for Dirty Drive Tuning for your thrusters. You’ll top out at over 600 meters per second when boosting, and not far short of 500 with 4 pips of power to the engines cruising. For a ship that’s as heavy as an Anaconda, that’s insanely fast, This will make it so if any AI ship chases you, you can leave them in the dust in seconds, and open the range enough that they’ll eventually forget about you.
This might sound crazy, but I swear it works. Run 4 Gimballed Multicanons on your Clipper. Give at least 2 or 3 of them a Thermal Effect to help bash down shields quicker. Once you’ve done that, go into your Contacts Panels, go to the Target Tab, and snipe the Powerplant of the other ship, this generally but not always, be done when you’ve got a shot at the middle of a ship. Bringing a Powerplant down to 0% integrity, then hitting it a few more times, will cause instant destruction regardless of Hull Integrity. This is where the speed and agility come into play. Find a target that’s distracted, get on their tail, batter their shields down, and blow up their Powerplant.
Using this sort of setup and strategy, I can reliably solo High Intensity Combat Zones with my Clipper and only have to do a refill of my ammo once as the kills come quick and easy if you pick your targets well.
As for how long Combat Zones will take with this setup… I don’t know what my best times are for Medium and High Intensity, but my average for Low Intensity is probably… 7 minutes? My record is 5 minutes with 9 kills.
