About

Gun Deck

Read full description

A classic deck building game has never been this fun. Each card represents a 3D weapon. Create your own luck. The more powerful cards you put in your pocket, the more good weapons you can put on the table. There are rumours that there is a super powerful weapon hidden in the game. The more you play, the faster you get to hard-to-reach rare cards. Shuffle your deck of cards, reveal a new card to hit the enemies that come your way. The next gun card would be more powerful or not. Find the best weapon for the weak points of the enemies. If you are lucky, the following gun card could be more powerful. Reward yourself as you complete each stage and equip yourself with new weapons to build a better deck of cards. There is both luck and strategy in this game.
