Bthamz: One Ashlander per person. There's several things you can do.

-Run back out
-Hold defensive positions
-Hide behind steam and obstacles
-Attack an Ashlander directly
-Attack an Ashlander stealthily 
-Attack the centurion
-Reason with an Ashlander
-Shoot the centurion's sensors, which may blind it

Everyone choose their own option, you guys can also suggest other ways to go about it. Dice roll when everyone decides.

Island surface update tomorrow.
