Key mappings If there are hardware buttons in your phone or tablet, then you can map them here.


Smoothing level Texture smoothing level (if you have old phone, select first level, for modern phones smoothing has almost no affect on FPS). To our taste, it is better to leave the second smoothing level, in order to preserve retro atmosphere better.
Gamma If even at maximum brightness of screen the image is too dark, here you can fix it.
Show crosshair Although, following the canons of Doom you will not have to aim precisely, you can still turn on the sight.

Since the release of the first version of the game, we have revised our views on the controls, and in this release we made them similar to controls of the games Shadowgun and Dead Trigger, which had become the de facto.

In the lower left corner is on–screen joystick, with which you can move forward, backward, left and right. In the lower right corner is fire button.

The entire right side of the screen can be used for rotating — you should put a finger on the screen and move it to the left / right. If you initially put your finger on the fire button, you can rotate and shoot at the same time.

In the upper left corner is game menu button. Here, you can change your weapon, enter the game code or exit to the main menu. Next to it are the indicators of health, armor and ammo. Beneath them taken keys indicators will be shown.

In the upper right corner there is button, with the help of which you can toggle minimap. The places you have visited and direction indicators are displayed on it.
