Man its been so fucken long before everything got fugged up.
Sneak : Wartime was still needed, in inventory, carry weight affected your sneak status, less weight = better sneak. Sneak perks disabled, NO SNEAK CHARACTER PERKS WERE FUCKEN NEEDED.
Best sneak was this and all that was needed is tweaking weapons it was able to use and a little more sneaky, but no you completely do a 180 tombstone up on this bitch and now server dead
Weapons were very balanced, some assault rifles were like spamming single shots, (HK G3 if I remember) AUG was viable AR, some needed tweaking, mainly AK's. SMGs were doomed other that skorpio with weapon closest to one hex mechanic. Ripper was still tearing shit up which needed adjustment (preferably more SEC cost per hit) Super Sledge and MPF were decent.
Sanic cannon was able to shoot through walls now if I remembered.
gotta watch old videos and read changelogs (you know, ones before si1man started helping)
and just get rid of the fucken particle accelerator, DSRs were enough already.
