DON'T MAKE A SOUND

Co-op horror in a pitch-black mine! Every sound you make draws a glowing sonar wave. It shows the walls... and tells the monsters where you are. SNEAK OR RUN - sneak to stay hidden, but you can barely see. Run and the tunnels light up, and the monsters hear you. 3 MONSTERS - the blind Hunter follows your steps, the sleeping Brute wakes up and charges at loud steps, the Bat screeches to find you. CO-OP FOR UP TO 4 - your friends' waves light up the dark. Grab a caught friend's helmet to save them. GRAB LOOT, GO DEEPER - every floor down makes your loot worth more. Escape now, or risk it all? THROW STONES - lure monsters away from your friends. SUPPLIES - rattles, echo darts, felt wraps, glowworms and tonics to outsmart the dark. Fix the lift with levers, a battery and beacons. Upgrade quiet boots, a bigger backpack and the echo sounder. Daily quests, depth records and wave skins.
