Alright, after seeing people mistake things like Adminplz's HUD for a Mod I have made a brief tutorial on how to make your screen look like that.
Let's get started...
/cg_drawgun 1/0- 1 enables the gun, 0 gets rid of it. Drawgun 1 is
here and drawgun 0 is
Here--Pros: Gives you a larger view of the enemies to the right. Cons-- you might forget what weapon you are using (lol)
/cg_drawteamoverlay 1/0- Gives you a small list in the top right hand corner (default) of your team's kill status. 1 is here:

--Pros: gives you easy access to glance at both your and your team's score without having to spend time using tab. Cons-- it's kinda small...
/cg_lagometer 1/0- 1 Enables it, 0 gets rid of it. /cg_lagometer 1 looks like this:

--Pros: you don't need to |TAB| to view your connection/ping. Cons-- Takes a tiny bit of your view. That's it though.
/cg_drawcrosshair Y/X- If the HUD you are using has a crosshair attached, this will work. /cg_drawcrosshair Y looks like this:

and /cg_drawcrosshair X looks like this:

Just a few thing's I wanted to go over. Thanks.
