This awesome strike only works on the Jungle stage. It doesn't really matter if you go first or second. So here's what you need to do:

1. Start a game on the Jungle stage

2. When it's your turn, go to the area that leads to the area below the bridge

3. Don't get to close to where the wall that's blocking your way to the area that's below the bridge (I would stop right where the guy is standing in that path that leads the the area that's below the bridge because you need to use the Rocket Launcher to blow up that wall and if you're standing to close, you'll get blown up as well)

4. Wait for the opponent to blow up the same wall that's on there side of the field

5. Use the Rocket Launcher and just aim straight at the wall and shoot a rocket (which will blow up the wall)

6. On your next turn, you just bring the second person you use right next to where the other two guys are standing and shoot a rocket

7. Finally, the rocket should go right above the little step there, dodge all of the obstacles, and hit your opponents hitting two or more people with just one rocket!

It's one awesome strike!
