Horizon

Horizon is a heavy carpet-bombing ground unit introduced in version 6.0. It is derived from the Ghoul Bomber but redesigned to drop clusters of bombs on enemy ground targets. Horizons have no item-carrying capacity, possess moderate health and light armor, and specialize in dealing area damage to structures and ground units rather than engaging air targets or transporting payloads.

As of the documented builds, a Horizon has 340 health, 3 armor, a physical footprint of 1.37×1.37 blocks (hitSize 11), and a targeting range of 17.5. Its movement is ground-only (it no longer has omni movement) and its internal speed was converted to game units equivalent to about 12.37 tiles/second in later builds. The unit detects ground enemies or blocks and will automatically begin targeting them; it cannot target air. Horizons carry no items (item capacity 0), a deliberate design choice that prevents blast-compound kamikaze strategies.

The Horizon’s offensive capability is delivered by bomb-style weapons that behave as slow, short-lived area bullets. Each weapon fires inaccuracy-prone projectiles (about 15° spread) that explode for 27 area damage with an effective radius of roughly 3.1 tiles, and they deal 13.5 damage against force fields. Bomb projectiles have a short lifetime (0.5 seconds / 30 ticks). Weapon behavior notes: they only fire while the unit is moving, the weapons do not rotate toward targets, and the firing pattern is described as two shots at 2.5/sec (expanded data lists a short reload interval of 12 ticks). Bombs are flagged as “blasted” and cannot hit aerial units.

Tactically, Horizons are strong at punching holes in defensive lines and destroying key infrastructure (for example, power nodes, turret supplies, or Reactor links) when they reach their targets. They are most effective in situations where enemy Scatter turrets and similar point-defense are sparse. However, they remain relatively fragile and are particularly vulnerable to Scatter; using Metaglass ammunition on Scatters increases their ability to stop Horizons. Cheap bait blocks like the Pulverizer, placed inside rings of Scatters, efficiently lure and eliminate Horizons. Poly units can intercept without risk while frontline repair units restore any structural damage. Parallax turrets can be used to pull or redirect Horizons that slip past outer defenses.

In allied or player use, Horizons offer high burst area damage for modest cost but are quickly outclassed by the Zenith once advanced reconstruction techs are available. Because Horizons cannot carry items, they cannot perform blast-bomb kamikaze runs, so their role is purely bombardment rather than payload delivery. The Horizon’s bombs are implemented as conventional bullet entities with very low velocity and AoE damage. The Horizon is also noted as the only unit on Serpulo with an item capacity of zero.
