Obliquity: The Trenches

From BoardGameGeek:

War is imminent. You and your opponent will battle head-to-head, trying to fashion the strongest trench, using secrecy and special cards to bolster your line. Will you try to strike first and declare war? Or will tensions reach the point of no return... The Trenches is a quick print-and-play card game that sees players building up their trench lines. Part face-off and part-puzzle, every card has its own placement peculiarities. Navigate around your cards and make minor adjustments to prepare your trench for the ultimate Advanced Cards. Cards so game-changing that sacrifices must be made just for the chance of fielding them. With each game only lasting 15 minutes, you and a friend can see the rise and fall of many trenches in only a short time. Just don't ever let them know exactly how many points you're working with... Good Luck, General. -description from the designer
