Strategy
Due to the strength of these aliens, it is recommended to first achieve at least all of Chapter 1's crystal treasure before attempting this stage.
Strategy 1 (ft. Castaway Cat)
Lineup: 3 Meatshields, Strong Anti-Alien Tankers, Castaway/Seafarer, Long range backup or wave immune units.
Stall the Kroxos and Shibaliens while leveling up your wallet. If they start to push, use an attacker to defeat them, let it die, and continue stalling. Once you get enough money and wallet level, start stacking Castaways. The more you stack, the easier it will be to get rid of Elizabeth.
Once you hit the base, deploy all you have against the enemies, while keeping your money in mind. When Elizabeth is defeated, use ranged units to get rid of the Ursamajors.
