The first map looks like a simple Quake version of the first bit of 'The Illhaven Saga' by Kew, a classic for Unreal, maybe it's a predecessor

Both of them are quite good. The first is a DM map, the second is more like a SP non linear map. An uncommon type of layout always feels a fresh breeze.

Fast paced combat, around ID difficulty if like me you just use the SG, good secrets with adequate rewards, no unfair ambushes, decent placing of enemies thanks to the layout and brushwork, amount of ammo/health/armor around ID maps, all the monsters can be killed with just shells, but more weapons are given. I recommend using mainly shells and nails, the explosives and cells just for fun.

Have to play the Quake TC these maps come from.

These levels are crap!

First of all, for 35 enemies, all of whom are grunts end enforcers, why would you place (attention!) 3 mega health packs, one quad, one green armour, two yellow armours and two red armours? Secondly, the layout is VERY confusing. You keep opening numerous doors/curtains by shooting some objects on the walls (they don't look like buttons) or you just shoot the door/curtain itself. In the second level finding the golden key might as well take you... forever, besides it is so freaking DARK!!! And the number of doors/curtains is overwhelming, there's no need for so many obstacles. The levels themselves look nice, but the gameplay interest is zero: all enemies are easy to kill, lots of powerups, the player keeps bumping into ridiculous amount of doors, and it's not clear at all where to go.

So, unless you wanna get really frustrated, don't play these two levels.
