What is Alien Defence - Save Area51?

Alien Defence - Save Area51 is an arcade-strategy game where players defend Area 51 from alien hordes. While the core gameplay is praised for being fun, the app suffers from a 2.9-star rating due to severe technical issues and aggressive monetization. It targets casual sci-fi fans but is currently losing users to more polished competitors due to its intrusive ad frequency and high-cost ad-removal options.
