About this game

The brochure said Verdant-7 was paradise. It forgot to mention the bugs.

Bugvalanche is a tower defense game where the enemy isn't a wave - it's an avalanche. Thousands of bugs pour down the roads like a living river, and only your colony wall stands in the way.

BUILD IT YOUR WAY
* No fixed slots: drag your weapons anywhere on open ground, turn them, and set how wide they fire.
* 8 weapons: Pulse Gunner, Plasma Torch, Arc Mortar, Shock Cannon, Cryo Sprayer, Tesla Pylon, Photon Lance - and the Proximity Mine, laid right on the road.
* Dots along the road show your coverage. Close the gaps, launch the defence and watch the swarm run into a wall of fire.

CALL IN THE MOTHERSHIP
* Rocket salvos, drone strafes, cryo bombs, carpet bombing, an orbital laser - and the Sunhammer, once per battle, very, very big.

LOSE, UPGRADE, WIN
* Every squashed bug pays, even when the wall falls.
* A huge upgrade tree with more than 120 upgrades in five branches: Armoury, Fortifications, Research, Mothership and Mining.
* Upgrades you can see: every weapon grows through four ever more imposing looks.

THE SWARM EVOLVES
* 50 levels across 9 regions: grassy valleys, frozen tundra, a glowing spore jungle, a volcanic rift, sun-baked dunes, crystal caverns, tidal shallows, a starship wreck and the Hive itself.
* 10 kinds of bugs with their own tricks: splitters that burst into three, shieldbacks that stop bullets, nurse moths that heal the swarm, bomb ticks, golden scarabs worth a fortune...
* 4 hive queens with moves of their own - and the Overmind waiting at the end.
* Swarm mutations: armoured, hungry, fertile.

KEEP PLAYING
* Heroic difficulty, the Endless Swarm, a daily challenge, daily quests and login rewards.
* 75 achievements, statistics and a Codex of every bug and weapon.
* Your worried robot sidekick B.O.B. briefs you before every level.

Plays offline. Ads are optional - you only see one when you choose to double your credits or repair the wall.

What’s new

• Endless Swarm: bugs no longer pile up in the bends or slip through the ground into the next lane
• Bugs on every map stay on the road – a bug pushed off it heads straight back
• Orbital Laser now stays on the swarm instead of drifting onto empty ground between roads
