ReadMe:This is a mod of Death Island for Halo PC. The only change made to this map is the assault rifle. it is now extremely powerful, but there is only one on the map. It is hidden on top of a hidden area on the map(just look up to see it). This a slightly modified version of Death Island. The mod adds a powerful assault rifle on the map and places teleporters in each base to reach it.
