The Club

Doing each level on Insane is not particularly difficult if you've already got a good grasp of the game. What I'll do is explain what each of the levels are and any quick tips.
You do not need to win the tournament .... just survive. You'll have 5 tries at each level.
It's possible to make a backup of your save on a USB stick, so if you are struggling with a level you don't have to start the whole tournament again. Just reload your save if you fail 5 times.

Level 1 : Sprint
Just play through the level, take your time and get to the end. No time limit

Level 2 : Survivor
Run straight forward and stand to the left of the right-hand ramp. Turn around and you should have a box to your right with the number 605 on it. You'll get 2 or 3 as you set up then I got nothing until I had 1 minute (of the 4 minutes) left. When you start to get a few if you go to the other ramp (so box 605 is in front of you) you should get no more after you kill any that can see you. I finished this level with only 3 kills and 70 health left

Level 3 : Sprint
Same idea as Level 1

Level 4 : Siege
You get 3 minutes 30 to do this and after the first 20 seconds you can go and make a cup of coffee till the timer runs out. From the start run forward and to the left. Stand next to the railing, behind the cone at the top of the stairs. You only need to kill 2 enemies and thats it done

Level 5 : Time Attack
Make it to the end before the time runs out. 3 laps. Shoot as many enemies (this gives you a 3 second bonus) as you can and just keep moving. Health Packs do not respawn in these levels.

Level 6 : Run The Gauntlet
Get to the end before the timer runs out. You get 1 minutes 30 to do it

You do not need to win the Tourney in any place, just pass all the levels. You have 5 tries per level to complete each match, so dont worry about winning 1st place.
Will earn achievement right after last round.
