I can't remember what was more awesome: dreamy AS50 TWS or hatcheting up the hacker who spawned it.
Also - if you don't know if a weapon is legit because you're excited/new/etc - no worries. but if you actually 100% know that a weapon does not exist in dayz proper and has in fact been hacked in by someone else- probably not OK to actually use it, ethically speaking.
Every story needs a villain. Enquire within.
