DerpDerp is a fantastically realistic extraterrestrial first-person shooter game. There are lots of games in the genre offering a wide variety of adventures and space wars. But this one is unique in many ways. You are thrown on one of the planets alone with lots of weapons loaded and a mission given. There seems to be no one else but is it really so? In fact, you've got to find out. What is going on this strange planet where you can see a lot of huge buildings and no living creatures? The reason is that not long ago all your soldiers were eliminated in a cruel way. And your war base is now absolutely isolated from the rest of the world. But who needs all those deaths and what is their primary goal? There are armies of aliens in Derp that will follow you to destroy all the humans and capture the territory. You need to be quick and brave, use your weapons properly and move fast. Get rid of the aliens and bring the peace back to the planet - this is your mission in Derp. Use control keys to move, jump and explore the location. Change your weapon and keep an eye on its amount. Dynamic and really scaring at times - the game will make you shudder and feel the danger as if the action happens right in front of you. The game fantastically imitates every move and gives you a great opportunity to struggle and travel where you want. You need to find out the number of alien monsters on the base's territory, locate them and neutralize. Every decision you make will influence your future progress so be careful and try not to lose life at the very beginning of the game.
