Deep End

From BoardGameGeek:

In Deep End, you and your team of marine biologists encounter a ravenous alien squid with the power to twist your psyche and pit you against one another as reality distorts. To escape, you must outwit the rest of the crew and rise to the surface before madness consumes you. Deep End is a thrilling, fast-paced shedding card game for 2 to 6 players, ages 8 and up. Dive into a battle of wits where tactics and chaos collide. Your goal is simple: be the first to shed your cards and warn the world of the horror below or will you let madness consume you and be lost forever in the Deep End? -description from the publisher
