made with main credit to @griffpatch 's multiplayer base for the multiplayer integration. This would not have been possible without it. ---change log--- 2/26/2014: 1.1b- added integration of shooting for players 1 and two. the other two players can only fly around (which is okay since there will probably not be three people playing anytime soon anyway). 2/26/2014: 1.1- added flight dynamics and x/y velocities, and other visual and mechanical attributes. 2/26/2014: 1.0-basic multiplayer base copied.
