In the deserts of Australia, further excavations to find more Australium have been made. RED (Reliable Excavation Demolition) have built a base to host this expedition. BLU has noticed this large base that had been built and decided the Australian would help them defeat the RED team. BLU has called on a team of deadly mercenaries to take the RED base in the name of Blutarch Mann. But RED isn't just going to stand by and let them take their base. Neither teams are going to give up easily.
Ive gone with an Australian desert theme as i am from Australia. I will be using http://forums.tf2maps.net/downloads.php?do=file&id=3217 and http://forums.tf2maps.net/downloads.php?do=file&id=2848
did you get explicit consent from the creators? you don't just need to give them credit but get consent that you can use it and that their creations become official. just a fyi and heads-up
Do not use Half-Life 2 textures in TF2, they look out of place and ugly. There is plenty of metal textures around in TF2 so try those.
I will make the skybox go out more and add a 3d desert skybox complete with kangaroo cut-outs and shrubs
