a fan spin-off of Gmod nextbots.
the game plays a little off compared to Gmod, due to being built on Roblox and not Source/HL2. As a result, Bhopping allows you to gain much more speed than it ever would in source. For example, running through glass gives you a speed boost if bhopping with sprint enabled.
My favorite bit is the map design. nn_weirdcore, nn_camberturn, nn_mall and nn_russia are some of my favorites. the OST is pretty good too (the shop theme especially), and the game (minus nn_weirdcore) does a good job of capturing that abandoned feel that source games typically have. It's also pretty graphicly impressive (for a Roblox game, that is) and makes use of Roblox's "Dynamic lighting" though granted i do play source games most of the time, so my standard for graphics is pretty low. most of the maps are derived from gmod maps. nn_mall=gm_mall_parking, nn_russia=gm_russia, so on and so forth
