CrossbowFortIcon Time for target practice!

The Crossbow Fort is an advanced Ranged Tower that appears in Kingdom Rush: Frontiers. It shoots farther and faster than the Tribal Axethrowers but deals less individual damage per shot.


"Trained under monastic discipline, these crossbow furies are masters of their craft."

The Crossbow Fort is a highly versatile unit that not only offers strong ranged DPS, but also can significantly boost all towers in range.

The Crossbow Fort has great range, and while less powerful than the Tribal Axethrowers it can deal its damage over a longer period of time. However, what distinguishes the Crossbow Fort are its great abilities.

Barrage has huge damage output, quickly firing a set of bolts that deal moderately high damage. The neat thing about this is that they can retarget nearby foes, offering useful crowd control, and also that barrage has a short cooldown. This practically doubles the Crossbow Fort's DPS, letting it readily weaken lesser foes or punch a hole in a bulkier fiend's health.

On the other hand, the Crossbow Fort also has Falconer. Falconer raises the Crossbow Fort's range and critical hit rate, making it more efficient (especially with the rapid fire rate of Barrage), but that isn't why it is useful. Falconer also boosts the range of other towers in range (this includes towers that fall in its range after the Falconer upgrade). As such, the Crossbow Fort has a useful support role than gives towers substantially more range and affords the player much more flexibility with creating chokepoints. Note that only the Crossbow Fort gets the critical hit chance, while all towers get the range boost.

It's worth noting that without its abilities, the Crossbow Fort is not particularly useful. Furthermore, while Barrage is strong and deals heavy damage, it is still physical, making it much weaker against armored foes. On top of that, Barrage has limited range when it comes to retargeting, potentially leading to missed shots if foes are spread out.

Range Edit


  • The Crossbow Fort is one of the most versatile advanced towers, and is useful in almost every situation.
  • It should be placed in key strategic points to allow its Falconer ability to buff as many towers as possible. On most stages, up to 4 towers can be buffed, including the Crossbow Fort itself. The most towers that can possibly be buffed at once is 9 on Dusk Chateau.
  • The Falconer bonus does not stack with multiple Crossbow Forts, e.g. a tower within range of two Crossbow Forts, one with Falconer Level 2 and one with Falconer Level 3, will only receive a 20% bonus to range from the higher-ranked tower.
  • Barrage is one of the most powerful abilities in the series due to its raw physical damage output. and short cooldown. When upgraded to Level 3, it can fire off 300-400 damage with each use, and almost doubles the DPS of the Crossbow Fort.
