Some games offer high quality pathos, drama and complex character dynamics. Others offer you the chance to beat hellspawn to death with their own arms. Guess which one this is.
Doom really is Doom here, offering nothing but non-stop brutal violence. It doesn't just dodge the trappings of a complex story, it openly thumbs its nose at the very idea of it, going out of its way to mock such ideas. Not only do you leap right in - skipping any opening cut-scene - and gun down three nearby mooks, but the protagonist actively avoids the serious story going on in the background; going so far as to cut off the mandatory radio support team and smash supposedly vital items.
