If you enjoy Alien Shooter , I recommend supporting the developer (Sigma Team) by purchasing the official version from Google Play or the developer's website. If you'd like tips for earning money legitimately in the game or help finding the official APK, let me know.
Buy the flamethrower and max out your Energy stat (which governs energy weapon damage). The flamethrower creates a wall of fire. With unlimited money, you can refill its expensive fuel constantly. Kite the alien horde through the fire and watch them disintegrate.
: Open your File Manager , find the downloaded .apk file, and tap it to begin installation.
