Find and push that button, dude! (top right corner)

By the way, I suggest renaming "Isida" into more appropriate "Isis" in english version of the game. http://en.wikipedia.org/wiki/Isis

Hi guys! I have an Isida m3 gun and I must say that it is very far from being overpowered now, especially if it is not on power-ups. Everything that you should do is stay away from Isida. If you are good enough in steering and moving backwards - you can easily kill it in 2-3 railgun shots. So I prefer railgun. I take Isida only when I have a slow-slow-slow framerate and it's impossible to aim.
