Citadelic

Citadelic is a wave-based survival game where you expand a base, manage resources and defend your main fortress against constantly evolving enemies. Each run differs, so you need to adapt your strategy to the attackers and the resources and rewards available.

Build and defend

At the start of each wave, you build and expand your base. Use intel to see the characteristics of incoming enemies and build defenses that exploit their weaknesses. During battle, you can use skills to support your defenses in a pinch; skills can be upgraded with ore and enhanced with augments.

Enemies drop ore, and you can also produce it with ore mines. Spend ore on new structures, repairs, upgrades and skills. Weapon factories, chemical laboratories and science facilities generate tech points. Balance resource production against defenses, and protect production buildings from attackers. Structures can be upgraded to improve their properties or changed into new building types.

Rewards and progression

At the end of each wave, choose one of five random rewards. These include augments, temporary effects and resource shipments. You can install augments on structures to gain their unique bonuses, and matching them to your strategy is essential.

Runs take place in short sessions. Surviving more waves earns experience and unlocks new base types for future runs. You can also unlock optional gameplay modifiers, each of which provides one advantage and one disadvantage, and combine them to change the gameplay and explore different strategies.

Challenges and statistics

Unlock harder difficulty modes that affect how enemies evolve, and survive as long as possible by exploiting their weaknesses. The game also records detailed statistics for your runs and awards medals for completing optional challenges.
