Nice video, the gamplay looks quite FUN, especially with all those powerful weapons
I like the fog element from the first environment, it really creates the feeling of anxiety.
The explosions are just perfect, couldn't be better if you ask me but isn't there a way to smoothly fade in/out the dynamic light that appears after each explosion so it wouldn't be just the light on/off effect.
The best part was the 'flame trower', burn baby burn ^^
Great stuff

Cheers
