Rescue is one of the scenarios of Mobilising Armies. As defined by Jagex: "This scenario requires you to be the first to save 28 TzHaar from their steaming fissures. This comes with a new command, 'Rescue'. Click this command and then click on a flailing TzHaar to save them from certain doom, or simply left-click on the TzHaar. You may also steal TzHaar from your opposition by clicking on the 'Steal' command and then an enemy's stock, which is by their command tent and lander on the outskirts of the map." Players must complete at least 1 round of Hoard in order to be able and play Rescue (it does not matter if the player loses the round).
The story is described as follows.
||Since the discovery of this archipelago, explorers have been finding all sorts of wonders. When a team arrived on one geologically unstable island, they found a colony of estranged TzHaar. The team were surprised to be approached by this usually self-sufficient race, who appealed for help in abandoning their island home. Apparently, the island is rapidly cooling and liable to sink into the ocean: the TzHaar are far from exceptional swimmers!
