Information is definitely out-dated, and you shouldn't really take it to heart.
Original Survival, also known as Survival, was the true first ever Gamemode to be added.
You had to survive for as long as you can until all survivors die, or wait 4 minutes until a rescue vehicle went into the map and another minute for it to leave.
This Gamemode basically contains what is now the new Survival and Rescue, and is technically no longer available onto the R2DA platform. This was the only Gamemode to be played during the early stages of the R2DA Pre-Demo.
- If you want to survive, you have to work with others.
- Original Survival was the first ever Gamemode for R2DA.
