Phew, this job really doesn't let up, not even for rookies... and that's just the way I like it!
Here's a rundown of all my solo encounters on my first day on the job; everything else has been mentioned by my fellow officers already.
First, right off the bat, after equipping my Liberator, I ran into the Hacker Slipstream Zamfir in California. I attempted to arrest him; he resisted, and a battle began. Zamfir called in an Outcast gunboat, Maseru, to assist him.
Despite Maseru being equipped with Dragonflies, he was unable to prevent me beating the Slipstream. Unfortunately, after Zamfir lost his last few nanobots, he began to circle around the missile boat, and I had to leave for Riverside without scoring a takedown.
Next, I encountered the Outcast Falcata Ferres As Dakarto in New York, aided and abetted by the unlawful Freelancer Lumen, flying an IMG gunboat. Both resisted arrest; Dakarto escaped, but, after I called in some heavier backup, the gunboat Lumen was quickly and painlessly destroyed.
Immediately afterwards, I ran slap-bang into the Lane Hacker zlippery by West Point as he was attacking Navy regulars. He resisted arrest (unsurprisingly enough), drew me away from West Point, and opened fire on me, but was taken down without any trouble.
Right towards the end of my fight with zlippery, a bizarre character showed up and opened up on both me and the Hacker - Russ, a Civilian (//Civilian ID at level 56) in a Raven Claw, mounting Corsair pulse weaponry and codename cannons; no transponder. He never spoke a word during the entire engagement, simply blasted away at my Liberator - unfortunately for him, I was much the better pilot. After Russ lost his last weapon to my questing missiles, he threw himself into the sun. My guncam seems to have been damaged by the sun's corona - I gave chase - so I regrettably don't have a screenshot of Russ' suicide, but I've got one here of his final moments.
Following that, I was called to West Point to establish a blockade; two Hacker Spyglasses were inbound to New York. For some reason, they never arrived, so I went back on patrol; I encountered the illegal and unlawful merc AI Beta 5 by the California gate. The android first fled from me, then opened up on me with Colada del Cids in California proper. I easily gained the upper hand; Beta 5 ended up spending most of the fight dodging around like the robotic coward he was, but still couldn't win, and finally threw himself into Los Angeles' atmosphere after I tore off his precious Corsair guns.
After I took Beta 5 to pieces, I got a call from the Chief - I'd made the SWAT team. I chose to join the Guardian wing - I am a fighter pilot, after all - and set out to equip myself. While en route to Illinois, I ran into an Order terrorist, Bertic, in a Nephthys by the Colorado - Bush lane. He, too, resisted arrest (what a surprise!), after much deliberation, and merrily blasted away with, oh how original, Colada del Cids - he didn't last ten seconds.
After I destroyed the Nephthys, Officer Bauer showed up on the scene - I asked him to collect the terrorist's pod while I finished arming my shiny new Guardian. After I tuned my fighter to my satisfaction at Springfield, I turned in for the night. That's about it for my first day as a cop. Lots of action to be had.
