So I've played for what I believe is around 6 hours so I'm going to give my feedback of the beta so far.

Okay so lets start, Other than the deafeningly loud start and welcome from whoever that guy was, I found my self in a menu that was pretty simple, easy to understand, pretty okay so far.
Start story, another deafeningly loud cutscene (I hadnt turned things down but jesus christ) and oh boy some character creation! Spent roughly 10 mins waiting at a black screen because nothing wanted to load and when it did load it took another 10 mins to load all the items. Not So bad, okay set of items to create a little me in game, hair styles suck *** and you've basically got Bald x3 and maybe some hair, the facial hair for guys is just kinda meh, you have these poorly animated bears that looks like either small bush, less bush, goatee and paedophile/porn star staches. Nothing too good but not really in the game for that. Cool sets of clothes, pretty poor looking faces and a somewhat dodgy system for selection item colours, moving the arrows across then moving mouse just resets back to whats selected so nothing breaking but pretty annoying.

Cool, Guys made time to start. Bit of a long load, I've got a pretty high end PC but i'll give it some slack as my HDD is a little iffy at the moment, LOUD *** cutscene again, pretty poor facial movements from characters, audio cut out a few times and I'm unsure as of why and the game basically buffered as if watching a youtube video with bad wifi. Cutscenes textures didnt load properly for the most part and couldnt keep up with the scenes, pretty clear it's struggling.

Okay time to play, I joined a friend as he was on and I mean I invited him so might as well! Another super long load but I'll slack it due to HDD so eventually it loads and it's all out of sync. Fair enough, it's beta its not really going to have too much support right now maybe but very clearly needs some work, de synced and crashed multiple times during this, he had these problems just as much if not worse than me and made the game kind of a pain to play. Maybe it was my end, I doubt it but who knows.

There we go, we're somewhat stable so we keep playing either way, it's got some pretty bland mechanics with some even blander stealth/combat. Nothing really pops out trying to fight an enemy, they seem to just appear out of no where no matter what you do anyway it's not really like it matters. Cool you've gone sneaky, everyone is dead but suddenly some guys just spawn and ah damn it's going tits up. Weapon customisation is pretty cool and has some nice amount of attachables, cool that you gotta find them and work hard to earn them. Game still crazy bad with no sync for most parts, enemies and civilians spawning out of thin air.

At this point it just feels like rambling so maybe I can TLR

It's a buggy mess clearly not intended for PC players. It lacks any depth for this small area of the larger world, the skills seem practically useless, everythign just breaks in a few taps of a gun, you have this awful height level-out when flying or even doing jumps that makes gravity look 5x stronger than it should be, the physics are utterly stupid in most ways like driving into a car and it goes back end up and across the map, thigns just spawn out of thin air and suddenly you've died cause you actually hit a car and 3 civvies, theres no structure so every thing you do feels pointless and just tedious, same repetitive gameplay as most open world games.

I was look forward to this game but wow. Apparently this was in development for 4 years or something right? Well you sure fooled me.
This may seem a little rambling on but I've not much sleep and cant words well, personally I did have some fun but thats just cause playing a game in the end though its a bitter boring taste the game leaves that makes me unwilling to want to continue.
