Empires of the Undergrowth is one of the more interesting strategy hybrids to come out of the indie space in recent years: part base-builder, part real-time swarm-commander, all ant colony. The core game tasks you with digging out underground nests, managing worker castes, and directing warrior swarms against rival insects, spiders, and other threats that would genuinely terrify you if they were scaled up. The Exploding Ants DLC layers a specific real-world ant species on top of that foundation, one known for a self-destruct mechanism used in actual defensive warfare. Slug Disco has translated that biology into a distinct tactical identity that changes how you approach both offense and defense. From a build-order perspective, the DLC shifts your calculus considerably. Standard colony play rewards attrition and numbers. Exploding Ants reward sacrifice-efficiency calculations: how many detonating units do you spend to hold a chokepoint, and at what resource cost? That sounds niche, but it opens up a genuinely different late-game where you are no longer just flooding corridors with soldiers. You are setting up kill-zones, baiting enemy pushes, and timing expendable units the way a tower-defense player times ability activations. Players who found the base game's mid-game combat repetitive will find this species adds a meaningful new decision layer. The base game already has strong fundamentals for newcomers, and this DLC does not abandon that. The tutorial structure in Empires of the Undergrowth is one of the better ones in the sim-strategy genre. It eases you into pheromone trail management and food chain economics before throwing harder encounters at you. The DLC species campaign follows the same pacing philosophy. You are not dropped into suicide-bombing with no context. The mechanics build up gradually, and the scenario design gives you room to experiment before punishing mistakes. If you have never touched the base game, starting there first still makes sense, but a returning player can jump into this DLC's content without much re-orientation. Where the DLC is less impressive is in sheer content volume. At 94% positive across a large review pool, the community reception is clearly strong, but some players note this is a focused species addition rather than a sweeping expansion. You are getting new campaign missions, a new ant type with a specific mechanic, and the novelty that comes with that. You are not getting new biomes, a reworked economy system, or significant AI improvements. The enemy AI in the base game is serviceable but not sophisticated by grand-strategy standards, and the DLC does not change that. If your main frustration with Empires of the Undergrowth was that enemy colonies felt scripted and reactive rather than genuinely adaptive, that criticism still applies here. For the strategy player who wants something tactically creative without a 200-hour learning curve, this DLC hits a specific niche well. The mod ecosystem around Empires of the Undergrowth has been growing steadily, and the exploding ant mechanics open up obvious design space for community scenarios involving large-scale defensive holdouts. Slug Disco has shown consistent post-launch support, which matters when evaluating whether a DLC is a dead-end purchase or part of a living game. Based on the track record, it looks like the latter. If you already own the base game and logged meaningful time with it, this is the kind of focused mechanical addition that earns its price without padding. Diego, Scout Team
