So I completed the tutorial. I played Survival. I played for about 1.5 hours to give the game a good and thorough play through. As I said previously the game is absolutely worth the $1.99 to remove the ads. There are no other costs. You get a fully premium experience after this single purchase.
Now to the game. You play a radar operator / weapons officer in some war torn area. You will find enemy fighters and bombers coming in from every direction to take out your base. There will be civilian traffic, friendly fighters who will engage enemy planes, and friendly supply planes that bring you power ups. The game provides a constant, nail biting, intense experience! It's effing awesome! You must tap each contact to identify them and then you'll know if you need to engage them. You have 3 types of weapons. A short range automatically firing chain gun system that takes out enemy missiles and planes close in. Then you have a long range, but slower to move and target artillery system that makes a wide area of damage. You just have to be careful not to blow up friendly or civilian traffic. And then you have the quicker to move and target missile system where you can target 3 individual targets and fire 3 missiles at a time. Again be careful not to blow up civilian or friendly traffic. Lol I keep accidentally killing civilians.
Then you have 3 power ups that increase the powers and width of your 3 main weapons. They are dropped off randomly by friendly planes while playing.
As I said the game gets really intense. Sometimes enemies will make hit and runs in packs. Zip in and out. There are cool voice overs that give the game an awesome atmosphere. You really have to manage all of your weapons and their direction and how they work and how fast they fire. As I said I've blown civilians out of the skies with missiles and artillery lol. You accumulate points for every enemy you shoot down and lose a ton of points for every friendly you shoot down. I love watching friendly fighters launch missiles at enemy bombers. I think that was a nice touch.
All in all its a unique game with a great premise and atmosphere with intense action oriented gameplay. The interface works. Once you pay the one price it's fully premium.
