Minigolf3 is a fun map where golfers (players as snipers, soldiers, demolition man or medics) shoot golf balls (people as civilians) into a hole. There is a secret on this map, it is on top of the light house on hole 6. Once on top of the lighthouse there is a button to press here:

Now you must run to hole 9 where there is a windmill, once there you go to the middle of the windmill, turn left, run forward a bit and look slightly to your left, there is a invisible wall there.

Walk through the wall and you will come out on hole eleven, go to the middle and jump into the volcano then duck to see underneath it.

Underneath the lava you will see an opening (not on my picture but it is behind me) this opening takes you to the creators of the map.

After checking out that go back into the lava and get 2 friends down the volcano with you (you need 2 golfers and 1 golf ball). Then go to the opposite side of the opening (with the map creators in) and go through yet another invisible wall.

This leads you to here:

Now here is a tricky part, both the golfers need to get to the corners opposite the square volcanic bit my screenshot shows. The hard part is there is an inivisible wall there so swim fairly close to the lava, go left or right, then follow the wall untill you get to the corner. Once there the golf ball needs to go through the square lava and then you will both be assigned pong players (player one and player two).

Then you swim back and go through the lava that your golf ball went through and it will take you to hole 19 which looks like this:

Drop into the hole (all 3 of you) and a new hole will be there with a pong symbol. (No one else but you three can use this because you three have been assigned the players)

Once you go into that side hole play pong!!!

Enjoy. :)
