About

Whisper Game

Features
Read full description

Whisper is a ship-building space roguelite where every run becomes a machine of your own design. Fight through escalating tiers, recover weapons and structural blocks, and rebuild your ship while the battle is still unfolding. What you salvage—and where you place it—changes how your ship flies, survives, and fights. BUILD DURING THE RUN Open your cargo, compare recovered parts, and deploy weapons, shields, utilities, and armor directly onto your ship. Balance power, thrust, mass, and coverage as the pressure rises. CONQUER THE MACHINES Reach Tier 60, face the Apex encounter, collect your spoils, then advance into harder Machines with equipment that continues beyond Tier 60. Replay conquered Machines or push deeper. DISCOVER AURA + TOY SYNERGIES Collect animated auras and tiny companions. Equip the right pairing and enter a Machine to reveal hidden combat synergies. Each week, an elemental Host features a discounted pairing and strengthens its signature effect. EXPLORE PROCEDURAL EXPEDITIONS Choose from nine scenario families with issued expedition rigs, sprawling structures, branching travel routes, time-based control events, staged waves, recovery objectives, and extraction. Deeper expeditions take longer and award larger payouts. RECOVER CABIN TECHNOLOGY Complete scenario milestones to unlock permanent Cabin Modules, install two at a time, and search sealed caches for rare technologies that cannot be earned through ordinary progression. CHASE YOUR BEST RUN Weekly and All Time leaderboards show the strongest pilots—and always show your personal best placement, even outside the top ten. KEEP GROWING Spend Upgrade Alloy on permanent profile improvements, stock run buffs, save your progress, and keep playing offline when the network disappears. Whisper is built for quick mobile runs, deep ship experimentation, and the irresistible question: how far can this design make it?
