The Exploding Ants DLC – Headline Features
The Exploding Ants DLC is now available from the Steam store. It includes not just exploding ants, but exploding termites as well! Both perform a remarkable function called Autothysis which can be toggled on and off like climbing and aphid collection. Once you have the DLC installed, the following features will be available to you:
Exploding Ants – Colobopsis explodens
Exploding ant soldiers are available as unlockable units in ereptor colonies. When threatened, they explode causing high damage and a concussive blast. As part of an ereptor colony, the exploding ant soldiers have the following upgrades available:
- A choice of Controlled Blast or Violent Blast, increasing the damage or radius of the explosion, respectively
- A choice of Chain Reaction or Persistent Secretions, increasing the damage of other exploding ants caught in the blast or leaving a pool of liquid that causes continual damage, respectively
Explodings ants are available as full colonies in custom games, remix mode and the extra level The Harvest – Firebreak:
- Colobopsis explodens majors do not explode, but take less damage from the front and have an underground-only ability. They will go stationary, and buff the armour of allied units around them
In The Harvest – Firebreak, exploding ants must eliminate an aggressive fire ant colony against the backdrop of two leafcutter ants bringing in their harvest. Find it in the Extra Levels section of the Arcade.
Exploding Termites – Neocapritermes taracua
Exploding termite workers are available as unlockable units in ereptor colonies. When threatened, they explode causing damage over time and confusion to enemies.
- Since they are workers, they will perform nest jobs as usual
- Workers are born inert but become explosive after a time, indicated by a change to their UI icon
- The older the worker is before it explodes, the more damage over time and the longer the confusion effect will be
As part of an ereptor colony, the exploding ant workers have the following upgrades available:
- A choice of Rapid Maturity or Accelerated Gland Filling, which reduces the time until they become explosive or speeds up the damage over time and confusion increase, respectively
- A choice of Extreme Toxins or Extreme Confusion, which increases the length of the damage over time or the confusion effect, respectively
Exploding termites are available as full colonies in custom games, remix mode and the extra level Front Line – No Ant’s Land:
- Neocapritermes taracua majors do not explode, but they have a dual ability called Asymmetric Snapping. Underground, this ability causes high damage to enemies. Above ground, it will sun an enemy and cause the termite itself to be flung back
- Exploding termites consume lignocellulose in a similar way to African termites, but they do not require the steps to process it into fungus and instead consume it directly
In Front Line – No Ant’s Land, a small colony of exploding termites must survive a number of days against the approaching lines of army ants. Find it in the Extra Levels section of the Arcade.
DLC – Supporter Pack
The Supporter Pack does not add anything that affects gameplay, but is intended for those who have expressed that they missed out on the original funding campaign way back in 2016. It includes the following items:
- Myrmecia ereptor gene thief skin – new models and animations for the gene thief ants. Includes both queen and worker models. Inspired by real-life bull ants (Myrmecia genus)
- Original Soundtrack – the Empires of the Undergrowth soundtrack, 170 minutes presented in 35 separate tracks and downloadable as uncompressed WAV files
- Sounds of the Undergrowth widget to listen to the music and voice-lines in-game, with adjustable sliders for intensity
- 7 4k wallpapers with multiple variations for a total of 16 wallpapers
- 19 emojis, with some based on the game’s achievement icons
- 12 portraits
