Coming with a smaller board than the base game, Tank Chess: Portable is a standalone expansion ideal for traveling, playing in reduced spaces, or in a time constraint. The games played on a 12 x 12 square board play out quicker, the gameplay is usually more dynamic, and tense, as the Command Tank's escape is looming from the first few turns, and clashes and first casualties can be expected, basically, from turn 2. You’ll want to pay close attention to corridors closing due to vehicle destruction at all times, as you don’t want to block your own pieces from preventing a quick escape of the opponent's Command Tank.
The box measures 15.5 x 15.5 x 4 cm, and it contains a double-sided board that measures 29 x 29 cm; both the box and the board are made out of thick cardboard – the same as the Standard box and boards. Inside, there is the same set of pieces and flags as in the Standard version (2 x 16 pieces), so you can create many completely different custom setups and get an infinitely replayable game out of this single expansion.
