A Sanctuary inspired sandbox map

Created By:
Spaceneil8

Description:
Oasis is heavily inspired from Sanctuary in Halo 2. It is built in the crypt of Sandbox and is inverse symmetrical. This map has been designed to offer the great nostalgic Sanctuary style gameplay in Halo 3. Oasis has been tweaked a multitude of times to perfect gameplay and offer the best possible Flag, Slayer and Bomb games. Enjoy :).
