Siege Line is a versus tower defence for 2–16 commanders. Everyone defends their own identical lane against the same wave clock, so nobody is waiting on a turn — you are always building, and always watching the strips down the side of the screen to see who is drowning.
Kills pay gold. Gold buys towers — or it buys RAIDERS you shove straight into a rival's lane, wearing your colour so they know exactly who sent them. Every one that reaches their gate costs them a life and pays you tribute, so a well-timed shipment is part sabotage, part investment. The catch is that gifts are tougher than anything in the wave and worth less when they die, so spite you can't afford just makes your rival richer.
At wave 9 the siege beast comes for every lane at once. It only has to reach your gate a single time, and no number of lives will save you — the only answer is a board good enough to bring it down before it walks the road.
Four towers, three ranks each, sell for 60% back. Build fast, watch your neighbours bleed, and be the last keep standing.
How to play Siege Line
GOAL — Be the last commander still standing. Every creep that reaches your gate costs one life; run out and you're eliminated. Survive the siege beast at wave 9 and hold more lives than anyone else.
BUILD — Click (or tap) a tower in the bottom row, then click the snow to place it. Never on the road. Keyboard works too: 1–4 pick a tower, arrows move the cursor, ENTER places.
UPGRADE / SELL — Click a tower you've already built to inspect it. Three ranks each, and selling refunds 60% of everything you sank into it. Keyboard: U to upgrade, X to sell.
TOWERS — BALLISTA, fast single bolts (twin bolts at rank 3). RIME SPIRE, chills what it hits so everything behind it backs up. AVALANCHE, heavy splash, but blind up close. STORM COIL, arcs between bodies — best where they bunch.
SEND — Tap a rival's strip to aim at them, then buy RAIDERS or an OGRE and it walks into their lane in your colour. Their leaks pay you tribute. Keyboard: Q and E to send, TAB to switch target.
WATCH — The ◉ button on a rival's strip shows you their whole wall, live. Useful, and a real risk: nothing is defending yours while you're looking.
THE SIEGE BEAST — Wave 9, every lane at once. Armoured, slow, and it only needs to get through once.
