The Riftline universe

Infinite worlds. One line.

Two universes were never meant to share a space. Watch the Rift tear open — the origin of every battle you'll fight.

The collision

Universes were meant to be alone.
They grew until they collided.

Where two worlds touch, a Rift tears open — and two universes cannot share the same space. So each one pours its monsters into the other to overwhelm it and survive. The last one standing takes the space.

The core loop

Build. Maze. Send.

One lane. One chance. Two minutes to turn a trickle of Æther into a wall of towers — then break the enemy with everything you've held back.

01

Build.

Raise towers along your line. Five elements, three tiers each — every upgrade reshapes how your defense bites.

02

Maze.

Place towers to fold the path back on itself. A longer maze means more hits landed — the map is your weapon.

03

Send.

Spend Æther to pour creeps through the Rift into the enemy's world. Each leak annexes their map and overloads their rift — push their Charge to 100% before they push yours.

Every leak overloads your Rift Charge, from 0% toward 100% — and swallows a piece of your world. Hit 100% and your rift explodes, erasing your universe.

Your arsenal

Five towers. Three tiers of power.

Each tower evolves across three levels — silhouette, energy and lethality grow with every upgrade. Mix elements to cover speed, armor and air.

The colliding worlds

Each match is one collision

No universe is the chosen one — each believes it is. Every world runs on its own physical law, its own color, its own monsters. New universe = new content, forever.

Law · Void / Lucidity

The Void

Our world. Believes it alone knows the truth. The violet that opened the first Rift.

#9B4DFF
Law · Fire / Combustion

The Embers

Fanatic purifiers. They burn worlds clean — and call it mercy.

#FF6A2B
Law · Death / Necrosis

The Shroud

"Already dead — therefore unkillable." Rot spreads where they leak.

#5CFF8F
Law · Ice / Crystal

The Frost

Cold, geometric order. Freezes the ground it claims into perfect silence.

#4DC9FF

Matchmaking is canon. Every game is a distinct cosmic event — two worlds collide, one absorbs the other, the portal closes.

Ways to collide

Hold the line, or fall

1 v 1

The Duel

Two universes, one Rift. Pure, symmetric, no hiding — out-build and out-send a single opponent until their world is yours.

4-player FFA

The Junction

Four worlds slam into the same point. Multiple Rifts tear open under pressure — last universe standing absorbs them all.
