Missile Silo

Sometimes lasers and little bombs just won't cut it. For really tough enemies, or enemy structures, you need a big missile. After buying and placing a missile silo, you'll need 10 canisters of argon gas and 10 advanced electronics to prime it. Warehouse droids automatically deliver these resources to the missile as they become available.
Each missile has a production countdown clock that shows when it will be ready to launch. Clicking on the missile brings up an info screen where you can see how much argon and electronics are still needed. This screen also includes a button to pause missile production (helpful if you need argon or electronics elsewhere). When the missile is finished and you are ready to launch it, click on it to bring up the info screen again. Click the targeting button and then click on the map where you want the missile to land. Ka-boom!
