Played the BIGPOWER.rar version, not sure if there is an end to this game. Or if there is any objective in this game.
Very fun! Sadly my PC already struggling to handle this game I had to stop playing.
The basic idea/objective is that you expand around the map using your tower, trying to reach the satellite dish that unlock the new towers and turrets. Eventually you unlock a 'Nuke' tower that can destroy the enemy spawners and the game is won once you've nuked all spawners. We had planned to have a little tutorial to make it clearer, but ran out of time. Thanks for playing.
