Quadro Barrel Defence

Quadro Barrel Defence is best played after downloading, rather than using the web-based version. You'll get three modes of play: Scenario, Survival, and Construct Mode. In scenario move you get 30 turns to destroy your enemies and build you defenses for victory. In Survival mode there is no saving the game and your weapons will come from Scenario mode, so play that first. In Construct mode you can cater the game to do what you want but it must be unlocked through making it through the other modes. This game is super involved and has both strategy and action to keep you playing for days!
