Counter-Strike: Global Offensive has a lot of custom maps. Seriously, browse its Steam Workshop (opens in new tab) page and see for yourself. We've talked about some of our favorites (opens in new tab) (all of which appear in our CS:GO sessions (opens in new tab) on our server), but a classic map layout we've yet to see a worthy update for is de_rats' bomb-defusal play in an oversized kitchen. DJ PC820 and TastySlopsicle's de_dolls_csgo (opens in new tab) is perhaps the best spiritual iteration we've spotted yet.
Instead of a kitchen, de_dolls_csgo takes us into a heavily pink bedroom which I assume is the property of a little girl, but the power of pink is genderless. Just like in rats, the jumbo furniture provides multiple nooks and alcoves for plinking across the map, including a doll house with furniture and a duct passage for moving around without exposing yourself to the AWPer's paradise of the main bedroom floor.
The map supports both classic and deathmatch play as well as bots for offline practice. You can easily download it by hitting the green "subscribe" button on its Workshop page (opens in new tab) .
