One of my favorite user levels now that was tough and some close calls
Going to copy my review from the video description:Title : The Attraction to All Things Uncertain
Filename : Kaiser_12.wad
Release date : August, 2004
Author : Samuel 'Kaiser' Villarreal
Played with GZDOOM 100% secrets no saves xD
This is a pretty tough level in terms of difficulty and not in a bad sense, it was very strategic. There seems to be a little more enemies than the classic Doom 2 maps but not overkill. Ammo and health is quite scarce and you have to use them smart, and in a strategic way or you could be out by the end (when you will need it most). Causing as many in-fights as possible helps. You have to evade some enemies at first while you explore the exterior for goodies and ammo to prepare you for battle. I think some demons are placed not to waste ammo on right away but to make you move as part of the gameplay here. There's also an interior part of the level which leads to its own exterior parts. Gives a sense of being open but connected, which is a familiar formula. I might say that this level reminded me some of a Doom 64 type of layout with the mazey routes, you can get lost at first with the backtracking before knowing the level. It still gives the classic feel overall keeps you on your toes even though there isn't always an enemy at first. The design and layout of this map was above average and has great structure. I played and died many times, I ended up finding all the secrets. It felt rewarding to win. I would say that this map would be a great map to play in co op Survival also, having more players and spiking the difficulty would probably offer some great gameplay.
