Base Defense: Free Base Building Game
Build walls, stop the raiders · Works on mobile & desktop · No download
Base Defense is a free survival strategy game where you protect your base core from raiders. You get a short build phase, then raiders arrive from every edge in bigger and tougher waves. Spend scrap on cheap wood walls, strong stone walls and automatic turrets, repair your plan between waves and see how long your base can hold out.
Base Defense is free to play on PlayQuestHQ with no download and no sign-up. It works on phones, tablets, laptops and desktop computers.
Pick a wood wall, stone wall or turret at the top, then tap the ground to build. Raiders attack your base core in waves. Earn scrap over time and from every raider you stop.
How to Play Base Defense
- Tap the game to start. You have 15 seconds before the first raid.
- Pick Wood wall, Stone wall or Turret in the top bar.
- Tap an empty square to build it, as long as you have enough scrap.
- Raiders walk to your core and break any wall in the way. Turrets shoot them automatically.
- Survive as many waves as you can before your core is destroyed.

Tips to Win
- Build your first turret right next to the core so it covers every side.
- Raiders take the easiest path, so use walls to funnel them past your turrets.
- Stone walls cost more but hold three times longer than wood.
- From wave 3, big brutes appear. They smash walls fast, so add turrets before then.
Base Defense Rules at a Glance
Base Defense is a survival game where you build walls and turrets with scrap and stop waves of raiders from destroying your core. The run ends when the core falls, so every scrap you earn should make the next wave easier to hold.
| Goal | Keep the core standing for as many waves as you can |
| First build | You get 15 seconds before the first raid arrives |
| Buildings | Wood walls, stone walls and turrets |
| Currency | Scrap, earned over time and from every raider stopped |
| Enemies | Raiders from every edge, with big brutes from wave 3 |
| Losing | The run ends when the core is destroyed |
| Score | Points for raiders stopped, plus a bonus for each wave survived |

Building a Funnel
Raiders walk the easiest path to your core and break walls that block them. Instead of boxing the core in completely, use walls to leave one long, open path and line it with turrets. Raiders then walk past your turrets for longer, and your walls last much longer because fewer raiders attack them.
How Scrap Works in Base Defense
Scrap is the only currency in Base Defense, and it arrives in three ways: slowly over time, 5 scrap for each raider your turrets stop, and 15 scrap for each brute.
Because scrap keeps flowing while you fight, time spent holding a wave is never wasted. Early scrap is best spent on a first turret beside the core, because a turret earns scrap from every raider it stops. After that, save stone walls for the routes brutes will take, since stone lasts about three times longer than wood. Cheap wood walls still matter: use them to bend the raider path so enemies walk past your turrets for longer.
Planning for the Brutes
From wave 3, big brutes join the raiders. They smash walls quickly and take many hits. Before wave 3, spend scrap on extra turrets near the core rather than more walls, and use stone walls only where brutes will pass close to your turrets.
Mistakes That End a Base Defense Run
Most Base Defense runs end for one of three reasons: the core is boxed in, the turrets are too few, or the brutes arrive before the base is ready.
- Sealing the core inside a full box of walls. Raiders then chew through the nearest wall instead of walking a long path past your turrets.
- Spending every scrap on walls and no scrap on turrets. Walls only slow raiders down, while turrets stop them and earn scrap back.
- Placing the first turret far from the core. Raiders arrive from every edge, so a turret beside the core covers every side.
- Ignoring wave 3. Brutes smash walls fast, so add turrets and stone walls on their routes before that wave starts.
Good to Know
