Vector TDX's defense in depth turns the classic turret setup into an exciting test of your strategy and ability to instantly select the right type of weapon to destroy geometric vectors. You have to manage the defense, trying to timely upgrade more than twenty types of guns at each stage of this high-tech marathon. Carefully monitor the direction of the enemy's attack and quickly build a defensive chain to prevent the vectors from breaking through to the finish line. For each wave reflection and successful strengthening of positions in Vector TDX, you are awarded game points. A quick reaction to changes in the composition of enemy forces and the correct calculation of the damage radius will help you cope with the growing onslaught.
