Enjoy!
Background: Stark is a company name created by Iron Man. Iron Man has joined forces with other Superheroes including Hulk, Spiderman and X-Men mutants - Wolverine, Storm, Emma Frost, Colossus, Nightcrawler, Shadowcat, Rogue and Gambit. Now the devious Dr. Doom and his Lethal Legion are launching a major assault on Stark Tower. Their aim is to completely take over!

Zone of War comprises the best of two worlds - the element of strategy building and development and the fun factor of a very intense war zone action game with 14 hectic levels. The idea is very simple; you are in charge of a fortress defense area and you are a first class Private. If you win a battle, you earn a promotion from Sergeant all the way up to an army General. But it takes several intense battles to get even reach the rank of Lieutenant! You can see your rank in the “Achievements” menu section. You have two machine guns – small and heavy. The smaller one has a faster turn and is mostly fit to defeat infantry troops. The heavy gun can be upgraded after every battle. Each battle you win earns you 3 points that can be used to upgrade your heavy gun. Good luck Soldier!
Upgrade Definitions: Damage – how much damage each of your shots create, Firespeed – how fast your guns shoot, Defense – how immune your fortress is to opponent attacks, and Mobility – how fast your guns can be turned one or the other direction. You can see Repair Base there as well (1 point is used for a full repair).
Tips: Keep one eye on the top left corner blue bar. It displays how much damage has been done to your fortress. It is a good idea to repair it once the bar is less than half blue, or else your defense system may get too weak during an attack and cause you to lose the battle. Try to upgrade your Damage and Firespeed in the beginning and then start sharing upgrade points for defense and mobility as the enemy attack gets heavier. This will save you from wasting precious points on “Base” repair in the beginning. Once the battle begins, concentrate on defeating heavy tanks and helicopters first as they inflict most of the damage on you. When the attack is getting too heavy for you, and you need some extra backup – you may call in Air Support by pressing the Spacebar button on your keyboard (There are 14 levels of play but air support can only be used 3 times in total).
Controls: To start shooting – left click and hold your computer mouse left button. The shooting direction is controlled using your mouse but don’t move it around too fast as your guns have a lag and cannot turn quickly. Aim by moving your mouse gradually from one target to the other. However, your small machine gun can turn very fast, and therefore you have a chance to take care of oncoming infantry while defeating the tanks at the same time. To call in Air Support, press Spacebar. If you need a break or to pause the game, press the Esc or 'P' key on your keyboard. Click the 'Resume' button to continue the battle.

War on Paper 2 is a physics-based shooting strategy game that will keep your mind occupied for hours. Find a solution on each level by logically solving the situation. You can proceed to the higher level only after you master the preceding one. You are playing as a yellow tank, whose mission is to destroy all of the enemy soldiers and tanks. You never shoot at any of your enemies directly. You either shoot to flip the bomb switch, or shoot the chain in order to drop a bomb on the enemy. Aim at the object using your computer mouse. Shot power is adjusted by moving your mouse closer or further, and once aimed - left click to shoot. Some switches are yours and some are your enemy’s. You will see that easily when you hit the switch and nothing happens – it means it is not yours. With each new level, you have to consider the situation, find a solution, and solve the problem in order to proceed to the next one. To replay the game, click the 'refresh' icon, located in the left upper corner of the game screen. The faster you finish a level, the more points you earn. However, speed is not of the utmost importance here. It is better to consider each of the steps you take and find the best solution to solve the situation (just like planning for a big battle). Good luck General!
How to Play: At the bottom of your screen, you have three controls. Use your computer mouse to click on the left & right arrows to aim in different directions.

This is an excellent online activity for children and grownups to help exercise and develop their creative and logical thinking skills in various problem situations using the experience they gain as they progress through the game (Understanding gravity, skillfully adjusting the angle and force of the shot, taking advantage of available aids in advancing though the levels etc.) Each brain-teasing level introduces new tasks and becomes more difficult. There are several types of balloons that you have to destroy with your cannon balls.

If a balloon is chained to the ground or a block, the chain can "usually" be smashed with one shot. However, some chains are so strong that they cannot be broken. Instead, the anchor points (blocks) must be blasted away. If the balloons are about to “get away” from your target area and range, you can take several shots very quickly, and pop (burst) them before they escape. You are not limited by the number of shots you can take but you are awarded a “medal” for passing a level within the minimum number of shots set for the level. Stay vigilant as some levels require your rapid reactions within a second or less; Otherwise, you will fail the level. Get ready to open your mind, and think outside of the box!
