The work needed depends heavily on how much you enjoy Fortix 2. After a couple of difficulty modes and/or Zombie mode you'll have succeeded by just playing the game. For me this one came naturally, but not everyone wants to spend hours of running through the land of Artalom for such a feat. For those I have a simple solution that takes pretty much no work at all.

For starters, you need to pick the right difficulty. You have to pick "Easy". Other difficulties don't work because of the time limit you get on each stage. On "Easy" there is no time limit which is precisely what we want.

• Click on "Profile" from the games start menu
  
• Click on "Easy"

Done? Great. That was the most difficult part of our strategy. Almost there. Just a few steps left.

• Start a new game or continue a previous one
  
• Pick any level you want

You should now be playing a level on "Easy". What most people usually do is running from one corner to another in order to gain miles. Should you do that? NO!! That kind of grinding is both boring, frustrating and is simply to ineffective.

What you should do is simply walk (in any direction) and let those miles pile up. You DON'T actually have to move to get miles. Walking into a corner or wall is enough. The mile counter will register that activity and you will be gaining miles with barely any brain activity at all :D

Want to remove the effort of holding down the button for walking? Fine. We can fix that to. Get some tape or something heavy and use it to put pressure on your walking button. Works just as well on keyboards as on gamepads.

Electric tape = SUCCESS!
