I looked around the moment I landed, trying to see if there's any weapons around.
It seems like this game focuses more on realism since the weapons don't exist as floating objects above the ground but rather as objects placed on the floor with no indicators that they were even there.
If you're not observant enough, you would definitely miss finding these equipment.
Fortunately for me, I have played games with this kind of setting before so I was able to adapt quickly.
Which was how I quickly found a small pistol near me with its accompanying bullets laying near it.
I quickly snatched up the weapon and touched the ammo that was 'absorbed' into me. That was when I realised something popped up at the edge of my vision showing a counter as well as an icon of the pistol.
That must be my current equipped weapon as well as my bullet counter.
