Here we go. First things first, Stagla Logo in the background.
Zombies carrying and throwing weapons
The other guy is definitely Chris' co-op partner, every other grunt in his sequences is wearing a mask.
The eyes along with Chris' quote about it regenerating makes me think of the G-virus
Three things
1. Baldy does have a pistol equipped.
2. The overall design here looks like a cross between a bandersnatch and a leech zombie.
3. The enemy is wearing a mask.
That palm strike is totally one of Weskers old moves.
Looks just like Alexia/Nosferatu, probably the T-Veronica virus.
New guy in the same environment that Chris goes to later in the trailer. I'm guessing Russia.
More masks.
Suspicious virus lines on new guys neck.
Masked bad guys injecting some virus into them, probably creating the bandersnatch looking guys.
One of Chris' buddies spontaneously bursts into flames, which reminds me of T-Veronica.
Chris clearly in the same area as new guy.
Even more masks.
New guy in China, catches Ashley on the motorcycle.
No clue here, just thought it was cool and wanted a better look. Leons inside the church that he was facing the naked zombies outside though, in the earlier shot where he kicks some.
Zombie dogs are back!
Again, no idea what this is, but wanted a better look. Maybe a mutation of that large, mutated Gigante looking thing?
That's all I could find. Hope it's helpful.
