I built a storage module and some defense modules (connector pieces that have a bunch of turrets that fire on attackers) on my HQ station in X4 plus I put several laser towers near it. They're just mk1 laser towers, so they're not very powerful, but they'll do for now. I then invested in an energy cell production module blueprint, which set me back 2 million credits (a very significant amount for me still at this stage), then built a couple defense modules and an energy cell production module on my sunrise flower farm station, which set me back another 750k or so in material costs and hiring a construction vessel.
The investments will be well worth it in the long run. Energy cells are used in the production of almost everything, so I'll be putting that blueprint to use a ton of times going forward. Adding energy cell production to my farm makes it almost self-sufficient, I only need to bring in water. The module will pay for itself in time in increased profits.
In other news, I captured my first ship today. I wasn't trying to capture it, but it happened that way. I'm doing a mission where I need to get shot at by at least 3 different types of weapons, to get data for Boso Ta, so that he can research shield mods for my ships. I purposely loaded up the cargo hold of my Buzzard heavy fighter with some fairly high value cargo, then cruised around shady sectors. Sure enough, a pirate scans me then tells me to drop my cargo. I scan him and I'm like "Brah, you're in a scout and I'm in a fully decked out heavy fighter, come and try to take my cargo." He was feeling lucky, so he attacked me. Very quickly, with some persuasion from my neutron gattling lasers, he changed his mind and bailed, leaving a battered ship behind. It's a cheap Kestrel, but what the heck, I claimed it and brought it back to my HQ to fix it up.
Later on I found an abandoned ship, an Osprey frigate! The X games always have some abandoned ships scattered about. They are usually in places that are either far out of the way or very dangerous (sometimes both). In this case, it was dangerous. The ship was stranded in an area with a bunch of Xenon (Terminators). I was in my Buzzard, so I got their attention then led them on a wild goose chase to draw them away from the ship. Once I got them far enough away, I ditched them and beelined back to the abandoned Osprey. Surprisingly enough, it wasn't even that beat up, hull damage was minimal, and it even had halfway decent engines and thrusters, plus 1 turret. No shields, though, so I had to sweat it out until I could get to an equipment dock or wharf (I went to a wharf), I did make it without incident. I didn't have enough money to fully equip the Osprey, since I spent most of my dough on the blueprint and station expansions, but I at least had enough to buy top of the line shields. I'm pretty excited to get a second frigate.
My fleet currently stands at 2 frigates, a heavy fighter, 2 scouts, and a freighter.
