Game controls

To prevent the alien invasion, you must set the following options. Firstly, select the mission and a battlefield. At the beginning, only a few battlefields are unlocked. As soon as you have proven that you can lead the defence troops, additional ones will be unlocked. You can subsequently determine the level of difficulty. This determines, among other things, how tough the opponents will be and how big your budget will be. With each promotion, more playgrounds and challenges are added. Finally, you have the option of requesting air support. Decide for yourself which weapons are useful for defence. Some monsters can only be fought effectively this way.

The aliens attack in several waves from the marked landing sites and want to take over the headquarter.

The upper game bar shows your budget, the number of attack waves and your available units. Each enemy unit that reaches the headquarter reduces the status by 10%.

A radar appears below so that you can recognise troop movements at an early stage.
The game bar at the bottom shows you the upcoming attack waves. You can also call up the settings on the left or set the standard zoom. On the right-hand side, you have the option of interrupting your own attack or switching between defence and air strike.

To build a defence emplacement, click on the corresponding position on the playground and select the unit from the menu. If your budget is sufficient, the unit is built and is immediately active.

To expand a defence unit, simply click on the corresponding unit and select the „Expand“ command from the menu.

If you no longer need the position, you can also select the „Sell“ command in the menu. You will be credited the remaining value.

In the event of an enemy air attack, you must react quickly and build air defence positions if necessary. Here we offer a quick option in the menu to swap units.

If an existing unit is selected, you can see the current range of the weapon and the range of the next level. If a unit is damaged by an air strike, you can also repair it right here.

In the first mission, battlefields 1 to 3 have a tutorial to familiarise you with the game and give you hints. In the other missions, the first battlefield always has a tutorial to introduce you to the new features.

The tutorial is switched off when a battlefield has been successfully completed.


If you have requested air support prior to the game and would like to use it, click on the combat mode button at the bottom right. Now mark the location on the playground and select the type of support in the menu. After confirmation, the attack takes place and the game switches back to defence mode.

The individual weapons are described in detail in the „Defence“ section.

Tower Arena: Time for heroes (Session 3)

Have you had enough of being bored and finally want to play a great modern strategy game? Then Tower Arena is exactly what you need. Here you will experience a strategy game at the highest level. The game is the successor to Strategy War and offers even more variations and tactics.


The game has three different types of terrain that require different strategies.

Firstly, there are playgrounds with open terrain. Try to extend the paths here so that the opponent has no way of reaching the headquarter directly. Perhaps you can take advantage of the terrain here to build better lines of defence.

On the other hand, there are fixed paths for the enemy. Here you have to position your troops so skilfully that the monsters are prevented from reaching the objective. But be careful with junctions and crossroads.

Finally, there are some playgrounds with open terrain and marked paths. Here you should make sure that the monsters use these paths to neutralise them.

The enemies get stronger with each wave of attack, so you have to keep reinforcing your troops.

Strategy War: Battle Game (Session 2)

Attention strategy game enthusiasts! Looking for a war game that will put your tactical skills to the ultimate test and keep you entertained for hours? Look no further! Play Strategy War. The game is the successor to Battle Alliance.

The defence

You have the following units at your disposal to prevent the monsters from conquering the headquarter. In addition to infantry and artillery, you also have some high-tech weapons, fortifications and mines. If you wish, you can also benefit from air support when things get tricky in battle.

PLASMA (For ground targets)

Use the Plasma weapon to attack monsters on the ground with pinpoint accuracy or to create obstacles. The purchase price is very low, so you need to carefully consider when to use this weapon.

LASER (For air & ground targets)

With the Laser weapon, you can fight monsters on the ground and in the air with pinpoint accuracy. For the price-performance ratio, you get a weapon with a moderate range and poor penetrating power.

GRENADE LAUNCHER (For ground targets)

With the Grenade Launcher, you can fight monsters on the ground with pinpoint accuracy. The purchase price is significantly higher. However, it is the perfect weapon in its category, but cannot be used to attack flying monsters.

CANNON (For ground targets)

This Cannon is suitable for performing area-wide ground attacks against monsters at long range. However, given its high purchase price, this weapon is very sluggish and useless at close range.

GUIDED MISSILE (For air & ground targets)

Use this Guided Missile to attack all monsters and UFOs at long range with pinpoint accuracy as well as with a high frequency. It is the perfect weapon for long distances. However, it is useless at short range.

AIR DEFENCE (For air targets)

This Air Defense weapon fights all flying monsters and UFOs with pinpoint accuracy and a high frequency at long range. However, the weapon is useless at short range.

FORCE FIELD (For ground targets)

This force field weapon has a unique technology to slow down monsters for a certain period of time. The opponents do not take any damage. This also comes at a price!

ELECTRIC TOWER (For air & ground targets)

The Electric Tower serves as an obstacle for all monsters and flying monsters avoid these areas because they cannot tolerate the electromagnetic waves.

POWER STATION (For your own troops)

Use the Power Station to supply the neighbouring units with additional energy. This increases the penetrating power of the weapons. Unfortunately, the running costs for operation are very high!


The Wall serves as an obstacle for monsters and is a simple and cheap way to extend troop movement. This object is no obstacle for flying monsters.

MINE (For ground targets)

The Mine fights all monsters (with the exception of slug-like monsters) on direct contact with the ground. The weapon has a good price-performance ratio.

SENSOR BOMB (For ground targets)

The Sensor bomb is suitable for ground targets and fights all monsters in the immediate proximity when the rotating laser beam is touched. Due to its effectiveness, the purchase price is very high.



All alien monsters are neutralised in a large area by the pungent-smelling hydrogen chloride gas. Even your own positions are destroyed!



All alien monsters are attacked and neutralised in a large area with phosphorus gas. Your own positions are protected!



All alien monsters can no longer fly due to the fine acid dust and crash, making it a very effective weapon against flying monsters.



All spider-like monsters are attacked and eliminated with the sodium bomb. This is a very effective weapon against monsters which react highly explosive!



All beetle-, caterpillar- or snail-like monsters are attacked with Hydragas and disabled for a short time.



Due to the high temperature at the area of impact, all alien monsters within a large area are destroyed on the ground.



The destructive effect of the bomb is mainly achieved by the large number of metal parts and combats all alien monsters on the ground within a small radius.



The devastating effect of the bomb is mainly achieved by the large number of metal parts and combats all alien monsters on the ground in a large radius.



All the alien monsters on the ground are prevented from continuing on their way by a heavy fog. There is no explosion, but the charge slowly burns down, producing a lot of smoke.



All pug-like monsters are disabled for a short time by generating sound waves with a high intensity that can lead to death.

Battle Alliance: Tower Defense (Session 1)

The enemy can also break through your defences using targeted airstrikes. These are indicated by corresponding black symbols at the top right. There are different weapons systems that the enemy can use. As soon as an airstrike is imminent, the area being targeted is marked in red. You will then have about 5 seconds to build your defences. All you have to do is build an anti-aircraft unit in the marked area. As soon as the area is shown in green, the units positioned there are safe against an attack.

The following air support is available to the enemy:

Surface Strike: The marked area is targeted. All defence units will be neutralised.

Targeted Strike: A defence unit will be targeted and either be destroyed, impaired, or damaged. If it is damaged, you will have about 5 seconds to repair the unit. Tap on the unit and select the „Repair“ option. However, in some cases the electronics of the defence unit are impaired and they fail for a certain amount of time.

Smoke Cloud: The marked area is targeted by smoke bombs.

Electric shock: The unit under attack will not be available for long because there has been interference with the electronics.

Blind Shells: Certain weapons systems misfire.
