About Eternal Rift Defense
BUILD THE MAZE. FIGHT INSIDE IT Eternal Rift Defense is a 3D tower defense RPG where you fight alongside the defenses you build. Shape enemy paths with walls, construct towers throughout your maze, and use your hero's abilities to hold the line. Battle through 50 rifts solo or with up to four players, level your towers from the battlefield, hunt powerful gear sets, and specialize your defender through heroes, talents, pets, and upgrades. You aren't watching the battle from above. You're fighting inside the defense BUILD THE MAZE Walls aren't just barriers, they're part of your build. Create winding paths, force enemies over traps, through kill zones, and decide where each tower will have the greatest impact. Towers built on your walls cost less, tying the shape of your maze directly to the shape of your defense. Build with twelve different defenses covering damage, control, economy, and support: Arrow reliable damage against ground and air. Cannon devastating splash damage at close range. Wizard specializes in destroying airborne enemies. Coin powerful single-target true damage. Ice slows advancing enemies. Tesla stuns enemies before they can break through. Poison delivers powerful critical strikes. Fire scales into devastating area damage. Support strengthens nearby towers. Research generates technology for your defense. Mine generates consistent gold income to build towers. Wall controls where the enemy is allowed to go. STAND ON YOUR TOWERS TO LEVEL THEM Your hero is part of the defense that has two unique abilities. Towers level up during each rift, and one of the fastest ways to power them is to physically stand on them. Your hero and slotted pet pour experience into the tower beneath you while the battle continues around you. Stay on your strongest tower and push its power even higher or abandon it to reinforce another part of the maze before the next wave breaks through. FOUR HEROES. FOUR WAYS TO DEFEND Choose from four heroes with different stats, abilities, and ways of supporting your defense. Knight a durable frontline defender who can slow every enemy on the battlefield and salvage valuable resources. Archer a fast-moving damage specialist who marks enemies and areas of the battlefield to dramatically increase incoming damage. Engineer manipulates the defense itself, creating walls and even swapping the positions of two towers in the middle of a wave. Mage teleports across the battlefield and channels experience…Read more
