Requires a Dummy account
Open the command console: ESC > Gear Icon > Under the keyboard tab select Advanced > Check off Enable Developer Console
Press the ` button to open the console and type:
map cp_foundry; hostname "boost"; sv_lan 0; sv_cheats 0; (I had to input this twice to be detected on my LAN for some reason)
That will create your match. Choose Scout on the Red Team. Then type the following command:
mp_teams_unbalance_limit 0; mp_idledealmethod 0; mp_idlemaxtime 0;
Make your dummy account a scout as well. Put yourself on the final capture point. Get the Dummy account to capture the neutral point and then capture the 2nd last point. Once captured, you will immediately start capturing the final point and unlock this achievement.
