ISL Champion achievment is worth 100 achievment points
Description: Score 100 points in a 'Sprites and Goblins' ISL Arena match without taking damage.
First you need to play the game single players a little bit and then check the front door for a letter saying you have unlocked ISL game play. It does not take long, finish the first 2 chapters to unlock.
Go to main meun, select multiplayer, then pick Simon as your character, then arena front yard, game type set to sprites and goblins and objective 100 points.
Press A button to start
Immediately run to the house where you are protected from the goblins
Turn and face the goblins trying to attack you.
Now, this is where you need to practice. Press and hold down the A button to make a super shot with your gun, then move the directional stick to chage aim and then let go of the A button. It will send out a super shot followed by a colud.
As you get good, you can advance towards the goblins while releasing the A button so that you can kill 4 to 6 goblins at a time.
Now, after you get good, you should know that 3 goblins that throw stuff will come out, it's random but normally they come out around 4 minutes. You may have to run out and kill them and run back to the safety of the house. It's risky, but with a little pracitce, you will have your achievment in no time.
Feel free to change the timer to 10min instead of an objective of 100, you may find it eaiser with the time setting.
