Okay, tried the new levels, and i got the hang of the shield enemies. I think 10 hp for the shield is fine (since you can just wire them to 2shot them) but it would be cool if we were able to shoot them in the back to kill them in one hit.
They are a good addition to the game since they can be used as "batteries" for the doors or the stuff you need to wire: they aren't very dangerous and they follow you around.
In the second chapter's 3rd level, i had a little resetting bug. i got killed in the room with the vans crashing in and spawning enemies until you charge the battery enough to get out, and when i got back in there, no enemies were spawning
The fact enemies are flanking you as the shield charges you is pretty neat
The SMG's ROF feels a little low imo
The guys throwing mollies are totally blocking the player's progression in some areas if you don't charge in the room, around corridors, like here:
Fast paced game, accuracy needed too, aimlets will get filtered
