The third installment of the series, Community Chest 3 boasts 32 maps made by 20 different authors from the Doom community. After one year of work, they have been made available for your enjoyment.
New from scratch
Too many to list
MAP28: Token Arch-Vile contains HOMs in the building with the bridge when viewed in OpenGL rendering modes. These are mandatory, as fixing them would otherwise ruin the bridge effect in software renderers. It also features no music whatsoever, but this was intentional; it was a decision on the author's part, and is not an oversight.
Several maps also contain sky transfer specials, introduced by the port Marine's Best Friend, which do not work in Boom; at the time they were designed, PrBoom and its brethren allowed sky transfers under Boom compatibility. This is merely a cosmetic issue, though, and does not affect gameplay. Apart from this, there are no other incompatibilities.
