So,...,...,...

Here we are once again.
With all the buzz surrounding video and computer games I thought I would throw something in there for anyone who needs it.

megatip: Sonic 2 (megadrive/genesis)

At the end of Aquatic Ruin Zone, Act 2, Robotnik shows up this time with a giant hammer which when striking one of the 2 totem poles which will rise up from the ground, will shoot an arrow at you!
To stay out of danger, jump on to one of the totem poles once they begin to rise up, that way you can jump on and destroy Robotnik before he has a chance to hurt Sonic.
