The ebuild is not in Portage (yet), but you can grab it directly from one of the developper's SVN.

# grep PORTDIR_OVERLAY /etc/make.conf | cut -d '=' -f 2
/usr/local/portage
# mkdir /usr/local/portage/games-action/
# cd /usr/local/portage/games-action/
# svn co https://arcon.svn.sourceforge.net/svnroot/arcon/trunk/overlay/games-action/teeworlds
# echo "games-action/teeworlds" >> /etc/portage/package.keywords

If you want to build the SVN version:

# emerge -av games-action/teeworlds

If you want the latest stable, use something like:

# ls teewars/*.ebuild
teeworlds/teeworlds-0.4.0.ebuild  teeworlds/teeworlds-0.4.1.ebuild  teeworlds/teeworlds-9999.ebuild
# emerge -av =games-action/teeworlds-0.4.1
