Mobilising Armies/Rescue
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).
This is the most competitive of all scenarios, and can be quite frustrating. Basically, you have to select a squad and then click on one of the few Tzhaar you can find on the island's openings. You have to be wary though, as other players can kidnap your Tzhaar, making them their own. If you're not careful, within a few seconds all of your hard-work would lay on hands of others, so watch your back.
What squads should I use?
Definitely light. It makes both rescuing and kidnapping faster, and helps you avoid defending squads. However, some heavy units to defend your Tzhaar might not be such a bad idea either.
What about Special Units?
Distractions work well here. Remember this isn't a combat scenario, so gliders and cannons aren't important. Build barricades to slow other squads down.
