The three single player maps are sm41asaki, sm41necros, and sm41_rpg respectively.

Asaki is probably the most interesting to me. You have to carefully descent through a series of beams and platforms, killing every enforcer you find (21 total) with a grenade launcher. Its a tricky process and a bit annoying but for a speed map i found the construction and layout to be relatively well thought out.

Necros and RPG are a bit less interesting. They both have careless and gratuitous monster placement and a simple and basic layout which is efficient and nothing more. Both appear to have custom textures, several from Doom in Necros (for some reason, they look quite bad) and some urban style texture in RPG which actually create an interesting atmosphere.

The DM maps are your typical speed map fare. Playable and ok for a few runs, but that's about it.

I'm going to give 2 for the whole pack with Asaki being the winner despite having the smallest monster count.
