Binding !medic is an easy but extremely effective way to boost your health, in best case faster than your enemy. You can bind much more commands, but !medic is the most frequently used one on our server. Just pick your favorite button, e.g. x in our example, press it ingame and your health will increase again.
Therefore, just follow these steps:
1. Open console.
2. Type: bind “x” “say !medic”
3. Only press x ingame and you will yell for a medic.
