Aiming and shooting from the hot-air balloon, stickman is defending his position from the incoming hordes of evil stickmen. What's unusual about Air Castle stick defense game at first sight, is that there's no castle on the ground to defend as we are used to in a classical defense. There are three battle modes: easy, normal and hard. We strongly suggest rookies to pick up the easy one at first. There are 20 levels in total and the game typically gets harder with higher levels. It's not too hard to shoot down stickmen on the ground, it's just that it easily gets too crowded below, especially if they shoot back at you or throw hand grenades. When you collect enough money, we suggest you visit a shop to buy some upgrades to improve your defense potential against either the land units, air units or water units. You can even buy a whole new flying vehicle. The choice of weapons is quite impressive, while the price ranges from 300$ to 2700$. Starting from level 4, land troops will be carrying rocket launchers, so unless you buy a decent upgrade expect to see your balloon full of bullet holes like Swiss cheese.
