We got familiar faces coming back, and it’s the shotgun-guy, and the heavy-weapon-dude.
The shotgun guy switches up the game a bit; you can’t avoid his shotgun blasts by crouching. The bullets however are slow, so you have time to jump over them or use a dodge. These guys can punish you if you get too used to crouching.
The heavy-weapon-dude AKA chaingunner is also a ranged roamer who will fire a stream of fast bullets in your direction.
The burst of 4 bullets is hard to avoid by jumping or running, crouching is a safer option. However crouching and waiting for all the bullets will leave you pinned down for a few seconds, which can be critical during an encounter. Chaingunners are also sturdier and can take a shotgun blast to the face.
The combination of these different zombified soldiers will keep you on your toes in the battlefield. So stay alert and see you soon.
