Sineus Arena Survivors — is a co-op Bullet Heaven base defense game where the entire map gradually turns into a siege against endless hordes of Cloud. In the center stands the Beacon — the only thing that still holds back the darkness. As long as it burns, the team has a chance to hold out. Players are constantly rushing around, shells are flying, towers are being built, and fortifications are collapsing, and any mistake quickly results in an enemy breakthrough right to the base. It's impossible to stand here and think calmly. Construction occurs during combat. You must simultaneously fend off waves, repair defenses, gather resources, and decide who will remain to defend the Beacon and who will risk venturing beyond the base to loot. The further you venture into dangerous areas, the greater the reward — chests, altars, rare materials, and artifacts can completely change the outcome of the next wave. The large number of heroes, weapons, and upgrades quickly turns runs into a chaotic mix of builds and roles. One character holds off the crowd at the walls, another clears the map with heavy weapons, and a third hauls resources back to the settlement. Over time, the base expands into a full-fledged fortified camp with towers, allied units, and defensive lines that must be held under constant pressure. Features of the game Co-op survival for up to 4 players. Protecting the Svetoch and building the base. Dangerous forays for resources and artifacts. Heroes, weapons, and dozens of build options.
