If you're ever having a hard time retaking B on Inferno, just build a better sightline. Created by Kinsi55, creator of CS:GO battle royale mod Go 4 The Kill, this mod demonstrates what CS:GO would play like if you could build ramps and platforms as readily as you can in Fortnite Battle Royale.
The result is both cathartic and extremely stupid, a strange shooter hybrid baby that combines one of the most hardcore point-and-click skill tests with the goofiest and most accessible battle royale game out there. Kinsi55 doesn't plan on a public release though; they say CS:GO's skyboxes are so small and buggy that most people would just get stuck, but I'll hold out hope yet. Gun game with fort-building sounds like a dream to me.
