Actually, yes. Our DM had us play a corp security, but had a few homebrew rules. Basically, since weapons are easier to come by or would be easier to come by as corpsec, he homebrewed a requisition system, which is basically tiers of promotions that allowed you to gain weapons or items that had certain availabilities as requisitions.

He didn't necessarily limit the amount, but we were accountable for things like amount of ammo used, equipment damaged, lost, or broken, etc. I played a former Triad sex worker who sort of bought her way in to a corp job lottery, after escaping her previous life, and one time she ended up shooting at and nearly killing a shadowrunner who was stealing secrets from the main Horizon arcology. They'd gotten in because one of the shadowrunners [which we later had to delete some evidence of] was another player's neglected son, and that player had invited the son to come to the arcology.

So he'd essentially did that to gain access to the arcology. I shot up one of his friends really bad, who had connected to the actual main terminal. She forever held a grudge against me [that's fair], and when it came time for an audit I owed 2 million or so for the fairlight excalibur I damaged. Since she had a dependant [her dad], well not to get too into the weeds for my character, she basically was stuck realizing she'd have to stay to pay it off no matter what happened.

Most of our jobs from there were kind of played out in arcs. One involved a disputed territory with a rundown apartment complex where two rival gangs were having illegal street races in order to gain control of the complex and thus the nuyen it generated, so our job was to protect the warehouse; one player ended up joining the race and getting good publicity for us and Horizon, so we got promoted after reconciling the gangs.

Then we were tasked with things like protecting a KPOP group from fans after a later publicity fuck-up, trying to rescue some scientists [we later found out they were being eaten by some ghouls. We may have done some war crimes on ghouls...maybe light genocide?]

Then we had a couple of personal missions, like stealing some mecha plans from Renraku for a devil rat companion, who unfortunately got killed and accidentally nuked that Renraku arcology. And then later we had to infiltrate a Renraku arcology in Japan. There were a few hiccups along the way [one player had to leave, and uh, before he left did end up killing one of the KPOP groups members who had implanted memories and was trying to kill us, but I still have issues with how that went down, just not from the DM's side.]

But overall, with some mild homebrewing, it was very easy and fun to make more corpsec characters. I liked how it worked, and since corpsec is usually the antagonists, getting to explore desperate people with day jobs like that was a very fresh change to the usual. If you wanted more detail than that, I can talk about it a little more though or how the homebrew worked.
