About the game
City defense is a fun defense game where you have to stop the hordes of protesters from taking over the city. As you progress in the game, the difficulties increase, more than one wave of protesters starts attacking, and new kinds of enemies like the Molotov throwers and stone palters unlock. But you are not a quitter, fight them back with even stronger forces, and don’t let them take over the city!

Tip #1 Use energy optimally
In the game, you get some amount of energy at the beginning which you have to use throughout the match to place your barricades, soldiers, and vehicles to stop the protesters from entering the city. Each time you kill a protester you earn 1 energy point. Each kind of defense uses a different amount of energy points. Barricades use only 3 energy points while a melee police officer uses 8 energy points and gunmen use 32 energy points. Use the energy points wisely, place the barricades only in places where they are needed. Do not deploy too many gunmen as they take up a lot of energy. Always try to deploy the melee officers in bulk as they are more efficient as a group compared to single officers.

Tip #2 Stay away from the white & blue line
In the game, there is a blue-and-white chequered line and your goal is to stop the protesters from clearing that line. To make it easier for yourself place your barricades as far from the chequered line as possible. So even if the protesters cross the barricades you will have some time to recover.

Tip #3 Placements of gunmen
Make sure to use your troop’s strengths to your advantage. Since you know that the gunmen can kill the enemies from proximity, place them behind the protesters. The protesters only move in the direction of the blue and white line. They do not turn around to fight the police officers, so place the gunmen right behind them, this way your gunmen will take out a lot of enemies without getting themselves killed.

Tip #4 Keep upgrading
At the end of each match, you earn coins and diamonds and use the coins to upgrade your barricades and your officers to their next level. You can also unlock new kinds of defenses like ninjas, tanks, electric barricades, etc using diamonds. The better troop you have the faster you will be able to finish the levels and unlock new worlds. After every 10 levels, a new world unlocks.

Tip #5 When in trouble
During the game, a helicopter flies over your head and if you click it, you can earn 400 more energy points by just watching a quick ad. If you are in trouble and the protesters are getting out of control when you are low on energy points just select this option. More such ways to tackle the protesters when they are getting out of control are the nuke option and the special unit option. You can access these options using diamonds.

So those are all the City Defense tips and tricks. Download the game through Google Play and The Apple Store and kill those faceless protesters.
