Ok, ye. You don't know what mp_teamplay is.

To turn it on, simply go to console (if you don't have console active, it's Options > Keyboard > Advanced > Enable Developer Console (check for a tick mark). Then press ~)

This is meant to assist you, not tell you how.
Ok?
Ok.
Anyways, engineers always place a tele just outside spawn.
Do that too, and then open the resupply locker.
Place your things like always. You may notice a friendly engi run to your dispenser or pick up ammo, because he has no metal.
A friendly engineer never upgrades his teleporter. Do that for him (optional, but if you want your teammates to get to the front lines faster then do it)
A friendly engi will not place a dispenser until his sentry is level 3. Help him to get the ammo you need.
A friendly engi places a teleporter (sometimes, not always) after his dispenser is done.
A friendly engi keeps hitting his sentry until one of his buildings is damaged and his sentry is not.
Engineers will not repair their teleporter. Yeah. They only care about their sentry and dispenser.
If a friendly engi is placing sentries but they keep dying, and then he dies, he will place his sentry next to yours. This is nice, for a sentry nest.
Your allies like to flock around the point and friendly buildings. Place your buildings next to the point to ensure maximum defense and spychecking.
Engineers will not tend to your buildings.
A friendly engineer will go to your dispenser to get metal if it is nearby.

thanks for looking at this. Rate and favorite (if you want).

Also, I'm not southern.
