Linebound

Four paths. One goal.

Choose your Linebound and find your play style. Each one brings unique abilities, strengths and tactical options. All four are free - always.

Rovan, the Vanguard

Vanguard

Rovan

Holds the wave right where it stands. The more enemies crowd around him, the tougher he gets - and the more gold he earns.

Aelys, the Arcanist

Arcanist

Aelys

Wipes out whole groups at once and buys time with thorned ground. Fragile up close: keep the wave at a distance.

Calder, the Deadeye

Deadeye

Calder

Brings down one hard target from further away than anyone else. Every shot on the same target hits harder than the last.

Vessa, the Shade

Shade

Vessa

The fastest Linebound on the line. Every kill builds momentum - keep moving, keep cutting, never stand still.

Gameplay

Easy to learn. Deep in strategy.

  1. 1

    Build your economy

    Gold coins stacked in front of an Anchor

    Every wave you send costs gold - and raises your income for good. Attack, economy, Linebound or defense: it is all the same gold.

  2. 2

    Send waves

    A wave of Bound marching down the line

    Put together your army and send it down your rival's line. Timing and composition are the key.

  3. 3

    Defend your line

    An Anchor shielded against attacking Bound

    Fight with your Linebound, send the right wave and stop every Bound before it reaches your Anchor.
