Played it again and i think im getting the hang of it. I like the idea of taking your time moving together through an area, miles better attacking then defending since that's just camping. The sights are still shit but i've learnt to fire in bursts so my ammo lasts longer. Still very annoying spotting an enemy shooting at him a few times then realising you have to reload, quite good the first time since i must have walked into their spawn, started shooting like a maniac, killed one but had to reload, hid behind a pillar but for some reason they never realised. Gets a bit frustrating see an enemy walking buy but you know you have to stay in cover to reload.
Glitches are annoying but hope they get fixed. Don't understand all the levelling and changing weapons but i haven't tried so just using the stock four options.
