Prepare for the battle to protect your base and complete your Lone Ops by taking down enemy troops. Upgrade your artillery and special attacks as needed.
Shoot enemies down and advance to the next level. As the game progresses more weapons become available and you will encounter more challenging enemies.
Load your rifle and shoot the flying skeets. Different colors of skeets represent different scores. Reach the goal by hitting the target and you will make it to the next level. Just don't shoot the pigeons. Good luck!
Keep your base safe from the huge advancing army using your trusty sniper rifle, air strikes and artillery. With each wave the invading army gets stronger, spend your money on the right upgrades and try to survive the war!
