Hi! I present to you the map “cs_lockdown_hotrap” for "Counter-Strike: Source".
I am game developer, but sometimes I do level design for some existing games, to gather experience or to keep fit.
This map is created on the basis of map from "Half-Life 2: Deathmatch". I
removed the nonworking elements and made a playable map to
"Counter-Strike: Source" (+ to "CS: GO").
So here is everything you need to play, plus special ambient sounds, new special decals and even new voice sounds.
I was able to return the original sound environment from "Half-Life 2" and also inserted more sounds in the general environment.- Now the map has become even more impressive and frightening. :)

Also I added a tactical places for snipers or for a sudden attack, plus some "landmarks" and even a map for radar, plus a 3D sky, opened
additional locations, created new areas, placed a lot of new objects and
edited entirely the navigation path of bots. Here on the map you will
see horror places, but also fun places and elements. And of course, I
created from scratch a few multilayered destructible columns. ;)
Also for this map I invented a special gameplay element, which I named as "Hot Trap" (for this, just I use existing physical objects of "Counter-Strike: Source" and "Half-Life-2").

According to the story of this map, terrorists stormed the prison and
freed the other dangerous criminals. They took as a hostages of some
prison staff who survived. In order to prevent the antiterrorist forces
to easily enter, the terrorists completely mined the whole prison with
explosive barrels, thereby making the "hot traps".
Use these traps against the anti-terrorist forces or against the terrorists! But be
careful that by yourself don`t get into the hot trap. And sometimes some
bots can blow themselves these traps and may die (sometimes should clear the way for them). Pay attention, if you accidentally killed your partner, then in the next round you will not be involved.
These "hot traps" you can use in any role, importantly should learn how to
use them. For this, watch the video on YouTube or experimenting at will:

I hardly worked on this map. I hope for you will be exciting to play.
Have a good hunting!
