In the 3D horror shooter game Into The Dead Trigger, you find yourself in the middle of a zombie apocalypse. You leave your apartment to explore the streets of a city full of zombies.
The goals change depending on the situation. Most of the time, the goal is to move around the map and get to the exit. Sometimes, you have to save other people. Use the WASD keys to move around. Shift lets you run, X lets you crouch, Q/E lets you lie down, and Space lets you jump. Hold RMB to look down the sights and LMB to fire. Use F to pick up items, R to reload, and G to throw grenades. Turning the scrolling wheel lets you switch between different weapons. You can also use the number row to choose the gun you want.
Have fun and good luck!
