A small experiment of a game, with the intention of learning networking features.
Up To 8 Players
Endless waves of enemies await. You're equipped with a gun (infinite) and grenades (not so infinite). Power ups and enemies alike will fall from the sky. Kills and deaths are individual, so try and top the scoreboard!
One game can be the server, while 7 others can then connect by ip. Chat system, scoreboard, joining in progress all featured.
(port forwarding may be necessary)
Originally this was just a flat surface, but what good are grenades if they don't blow up stuff? Create traps for enemies to fall into, then blow them all up at once with a well placed grenade!
