One of the best shooting games and action games we have had on our website in quite a while is the game on the page of which you find yourself right now, a game that is entitled Madness Sierra Nevada, and which we believe you are going to have an amazing time with, since we can say the same thing about our own experience with it, and we have to admit that it is the fact we enjoyed the game so much that has made us bring it over for you all in the first place. We will explain right here and now what it is you have to do in the game, so do not hesitate to read this to the end! You are going to be surrounded by enemies, as there are lots of them in each room you are going to enter. You have to sneak up on them and attack them first, grabbing their weapons and taking them out, and if you let them surround you by too big a number, you will probably get killed, so always be moving. Move using the WASD keys, pick up or throw weapon with the right mouse button, use the left mouse button to fire, left shit to look further, and use the space bar to finish the enemy if they are stunned. Good luck to each and every one of you!
