well, ive got one:
the body of a green clone did that
thats what you get for shooting 1000kg bullets at 90 meters per second. he completely obliterated my base and needless to say, i heard a lot of bone-crunch and splatter sound
the lines you see in the ground are from concrete/dirt/gold particles reacting to 200 megajoules force (200,000,000 joules worth of kinetic energy) or nearly 5 gigatons weight, giving them an incredible speed (probably about 2000-5000 m/s) making them penetrate anything they hit. some debris even penetrated to the player 2 base (upper part of screenshot)
about the "tunnel" on the left.. i have no idea how it got there, since the green clone didnt crash there.. perhaps some crazy ricochet :S
oh yeah, fps during and after the crash = slideshow
post yours!!
