I am a really slow hobby mapper so when I throw this idea out there it is more with the dream that the concept entices you all (the mapping Community) than it being my own personal initiative and open invite.
I think it'd be fantastic to combine 10-11 great Community mappers (or a cross-over between TWI Mapping-overachievers and the Community) to make one Hold-Out style map with a general concept behind it: the Portal gun. The small areas could thereby be prepared separately without any real cohesion other than a blue exit and orange entry portal. An Aperture Science lab would of course be best for the starting player spawn.
