Also, re: looks like a Doom 3 level. Have you played Doom 3 recently? The levels in that game were as small, as linear and as narrow as they come, with little to no exploration. They gave Half-Life 2's levels a run for their money. Doom 4 has the balls to provide big interconnected levels, sadly full of arenas, in a world of dreary AAA FPS titles filled with dull linear maps so the average dumbfuck gamer cannot get lost. No, I'll take Doom 4's sprawling levels over Doom 3's tiny linear levels any day of the week. The focus on arenas is bothersome but other than that I think Doom 4's levels are definitely going in the right direction and are clearly the game's strongest aspect. I think arenas are pretty cool when used sporadically, hell I use some myself, but Doom 4 just has too many of them, yes.
The main issue are the game's mechanics that undermine the level design's qualities, mostly the piñata system. There's little to no point in scouring maps to get health (something TB says in his video and his conclusion I hugely disagree with). In older Doom games you'd find Soulspheres, armor, weapons and stuff; here's it's mostly collectibles. Were the piñata system not there at all these secrets would be filled with good ol' items. I get the idea of always staying in battle and it sounds nice on paper, but this system was not the right choice because of that. It's like you have two different game designs clashing here. That and monsters are not used to their maximum potential, even if they do move around pretty quickly to catch the player which something I was pleasantly surprised to see.
