Mods-to-get for new players:

PHX1+2+3
WireMod
Combine model pack
SG-mod

IMO, SG-mod is not very good because the weapons are overpowered, but the gates are a cool thing.

Next up, how to create a basic car (Normal and Wired).

I will add links and instructions on how to install everything later.

By the way,

I found it easier to relocate the Q menu to the Tab button and the "Show players" screen to F5, because this way, I can use the hotkeys I am used to (I use Q to switch weapons).
