BEST STRATEGY TO BEAT MEDIUM LEVEL IN DUNGEON DEFENSE Game We have 3 gates in the game, let say gate 1 (first gate), gate 2nd (Middle gate) and gate 3 (last gate before your final defense) In Front of First Gate (Gate 1) : Except left side in front of the gate put sword units every where and upgrade only two sword units here upto 75 gold. Once you collected enough gold (300) immediately use it to put archer on the empty place on left hand side of the first gate (in front). So in this set up archer is in between two sword units and on the left hand corner of the gate. Once you collected enough gold, first update the archer to its maximum limit and then the sword unit on the right hand side of archer with axes. Keep collecting gold and upgrade all the swords with axes. Further upgrade the axes to its maximum limit on both side of the archer and only upgrade far right side axes upto 450 gold. Behind Gate First: Once you collected enough gold, then put axes on the left hand side behind the gate and put archer unit on its right hand side. Upgrade both of them to their maximum limit. Position of axes and archer behind Gate 1 is very important. Front of second Gate (middle gate): Place axes in the front two sites and archer on the back two sides. Here be very careful, do not waste gold on upgrading axes, but upgrade the archer to its maximum. You need to save atleast 1200 gold here when the 17 wave attack comes to give life to axes and further need to upgrade one of the axes upto 450 gold. This is very important. If you think game is too fast paced here then paus it and see where you need to add unit or add gold. Behind Second and middle Gate: Just behind the gate and right hand side put one axes and on its right hand side put one archer (do not upgrade both of them as you need gold to give life to axes in front of the gate during 17 wave attack). Front of Third Gate: Do not put anything on right hand side and front of third gate but put one axes on the left hand side. Here you do not need to upgrade axes. During the 17 WAVE ATTACK: Now the key here is to have enough gold as I mentioned in Middle and Second Gate (at least save 1200 to give life to both the axes when they are dead, 450 gold to upgrade one of the axes after giving it second life and further 600 or 1200 gold to give life to axes in front of third and final gate). You will end up in that much gold which I mentioned above if you follow exactly the above strategy. I beated all the 20 level with this strategy for medium level. GOOD LUCK
