## What is Trenchline?

The horde is coming. Your fortress is all that stands in its way.

Trenchline is a tower-defense game where the zombie horde comes at you across three battlefields, and you decide where the line holds. Build anywhere on the battlefield, upgrade as the waves grow, and call in airstrikes when the pressure gets too much.

BUILD ANYWHERE
• Riflemen you can march around the map, rapid-fire machine-gun towers, splash-damage cannons, and sandbags to funnel the horde
• Drag to place, rotate sandbags, extend a wall in one tap
• Zombies path around your walls: leave a gap and they pour straight into your kill zone; seal it off and they start tearing through
• Upgrade every defense three times mid-battle
• Hills block the way; high ground gives your gunners extra range

THREE BATTLEFIELDS
• Open Field: attacks from every side
• The Gorge: hordes from both ends of a narrow canyon
• River Crossing: hold the bridges, the only way over the river

SURVIVE 20 WAVES
• Every wave is bigger and tougher than the last, building to a final wave that floods the map
• Fast runners, steady walkers and heavy brutes that shrug off hits
• Cannon blasts send zombies flying; airstrikes carpet-bomb a whole area
• HQ about to fall? Revive it and fight on, as often as you can afford: each revive costs more
• Clear wave 20 to unlock Endless mode on that map: the horde never stops, and your best wave is kept
• Your best wave on each map goes on the leaderboards

FEEL EVERY SHOT
• Tracer fire, brass casings piling up at your gunners' feet, machine-gun rounds that punch through the front rank
• Towers sweep the field, lock onto the first zombie in range and open up

UPGRADE YOUR ARMORY
• Earn Ordnance Points by reaching wave milestones
• Spend them on permanent Mk upgrades for soldiers, machine-gun towers, cannons and sandbags — every one you build in future runs starts stronger

COME BACK EVERY DAY
• Daily login rewards and three new missions every day
• 19 achievements to earn
• Checkpoints at waves 5, 10 and 15: a lost run picks up from the last one
• Cloud save: your progress follows you to a new phone

PLAY YOUR WAY
• No account and no internet connection needed to play
• No forced ads: watch a short video only when you want a reward
• 9 languages: English, 简体中文, 繁體中文, 日本語, 한국어, Français, Deutsch, Italiano, Español

Optional in-app purchases: Gold (whatever you don't spend carries over to your next run), Ordnance Points, a one-time Starter Pack and the Commander Pack.
