Defense games come down to one question: can you hold the line? In this section you build turrets, grow your army through number gates and stop combat robots, drone swarms and infected waves from reaching your base. From night sieges to ruined highways and space fronts, everything plays in your browser with no download.
Tower and turret defense
- Zombie Tower Defense: build autocannons, cryo and tesla coils along the road and stop the horde before it reaches the bunker; four maps, twenty waves.
- Last Fortress: upgrade a single turret base through a night siege and buy breathing room with an EMP blast.
- Merge Turrets: merge turrets of the same level into railguns, missile pods and tesla towers while robots march on your shield down five lanes.
- Arrow Storm: Mech Siege: aim your railgun, multiply energy bolts through ×2 and ×3 fields and shred the robots storming your wall across 30 levels.
- Ball Storm: bounce plasma balls to break armored numbered blocks before they reach the floor.
Army growth and action defense
- Number Army: shoot number gates to grow your tactical squad, tear down the descending machine wall and face a boss machine every fifth wave.
- Crowd Battle: multiply a robot squad through energy gates on a 3D street and take down hostile squads and the war mech.
- Zombie Army Run: grow your squad through gates, clear infected hordes and reach the evac chopper.
- Zombie Survivor: survive five minutes with weapons that fire on their own.
- Zombie Highway Defense: clear the highway with the turrets on your armored truck.
- Space Defender: drag your gunship to shoot down drone swarms, kamikaze hunters and mothership bosses.
Strategy tips
- Invest in income upgrades early, then switch to damage.
- Do the math at every gate: ×2 on a small army can be weaker than +30 on a big one.
- Only turn on HARD mode once normal mode feels comfortable.
