About the game
Fortress Frontline is a tower defense game for phones and desktop browsers, inspired by Kingdom Rush. Build towers on stone spots beside winding roads and stop waves of monsters before they reach your castle gate. It has a rich top-down cartoon look with spell effects, explosions and lightning, and it plays in both portrait and landscape.
There are 30 handcrafted levels across 4 worlds: Greenvale, Sandspire Dunes, Frostpeak Pass and Ashen Wastes. Every world ends with a boss: the Gorehorn Warlord, the Sandmaw Worm, Varkoth the Lich King and Infernax the Fire Drake. You earn up to 3 stars per level and spend them in a permanent upgrade tree, and endless mode tests how many waves you can survive.
How to play
- Tap an empty stone spot to open the build menu. Tap a tower once to see its stats, then tap again to build it.
- Archers hit ground and air, Artillery deals splash damage to ground troops, Mages pierce armour and Frost towers slow enemies.
- Tap a tower to upgrade it. After 3 tiers, choose 1 of 2 specialised branches, such as the Ranger Lodge or the Volley Bastion, or the Storm Spire or the Void Obelisk.
- Tap the skull flag (or Next Wave) to call the next wave early. You get bonus coins and shorter ability cooldowns.
- Use Meteor Strike to blast groups and Reinforcements to block the road with soldiers. Both recharge over time.
- Watch for healers, splitters, burrowers, summoners and flyers, and keep 18 or more lives for three stars.
