Survival vs Campaign

The Survival mode and the Colony misions of the Campaign are very similar, with the following differences.

Survival

• Mayors of the Colony: After reaching a specific number of Colonists, the player is given a choice between 2 randomly picked Mayors (one male, one female) of the appropriate level. Level I at 30 Colonists, Level II at 200, Level III at 600 and Level IV at 1200 Colonists. Each Mayor provides a minor bonus to the Colony. There are no Mayors in the Campaign.
• Final Swarm: Once the player is close to their time goal, the message will pop up saying "Infected come from all directions! THEY ARE BILLIONS!!" warning them about the final attack of the game. This is the biggest and most difficult attack to repel of all swarms by far. Most Campaign missions doesn't feature the Final Swarm, but have various Victory conditions, always featuring target Colonist number (population) goal, and maximum number of days to accomplish all goals.

Campaign

• Tech Tree: In Survival, everything is unlocked from the start, the player just needs to perform in-game research at Wood Workshop, Stone Workshop, and Foundry. In the Campaign, only very basic stuff is available at the start, everything else must be unlocked. On the other side, many technologies provide significant bonuses to the units/buildings, which are unavailable in Survival.
• Train: In Survival, the Colonist dwellings are inhabitated immediately upon construction. In the Campaign, the player has to wait for the Train, which arrives only every 24 hours. On the positive side, after corresponding Tech-tree unlocks, the Train can also bring resources for the Colony and even a Wasp.

	Colonist	Command Center 10, Hunter/Fisherman 2, Tent 4, Cottage 8, St.House 16, Farm 12, Adv.Farm 24, Crystal Palace 60	-	Colonists are the total population of the Colony.
	Worker	Command Center 10, Tent 2, Cottage 4, St.House 8, Inn 100	all army, most buildings	Workers are used to operate buildings. Also each army unit consumes 1 Worker.

	Energy	Command Center 30+, Mill 30, Adv.Mill 60, Power Plant 160, Lightning Spire 800	most buildings	Energy is needed to power Colony's buildings. Buildings and structures can only be built inside the energy distribution area, which is extended by building Tesla Towers.
	Gold	Command Center 200, Tent 8+, Cottage 18+, St.House 40+, Quarry 10-100+, Adv.Quarry 20-200+	all army, most buildings	Gold is mostly generated by Colonists, and is used for everything. Some special buildings like Bank, Market, or Inn can generate Gold too.
	Wood	Sawmill 1-20+	Power Plant -10, Inn -30, Atlas Transmutator -20	Wood is the most useful resource in the early game. Wood Walls, Cottages, Farms and the Wood Workshop will use up large quantities of Wood.
	Stone	Quarry 1-10+, Adv.Quarry 2-20+	Atlas Transmutator -20	Except the Soldiers Center, Stone is mostly used in the mid-game, after the player builds a Stone Workshop.
	Iron	Quarry 1-10+, Adv.Quarry 2-20+	Atlas Transmutator -10	Iron is used early-mid game to train Soldiers and Snipers. It becomes more important as the player enters late game.
	Oil	Oil Platform 10+, Atlas Transmutator 40	Lucifer/Thanatos -1, Titan -2, Mutant -5, Victorious -10	Oil is a late game resource. All units from the Engineering Center need Oil. If Oil-income in the Colony is negative, the Gold maintenance cost of "unsupplied" units is doubled.

Villages of Doom

Villages of Doom are large "nests" of infected.

There is not enough Research Points in the game to research everything – you will be able to research only about 70% of the available technologies. Priority hints at what to focus on, though subjective. However two technologies are absolutely neccessary to unlock early: Cereal Farming and Plasma Spheres. Without these, missions will be unwinnable even on Easy.

There is a total of 48 mission in the Campaign. Of those, 23 are Colony missions, 10 Hero missions, and 15 Swarm missions.

Colony Missions

Colony missions require the commander to build up a colony from the Command Center and establish a foothold in the region. These missions are akin to Survival Mode.

Number of days to complete mission is modified based on difficulty: Easy 120%, Accessible 110%, Challenging 100%, Hard 95%, Brutal 88%, Nightmare & Apocalypse 80%. Special infected types are listed except Walkers, Runners, and Executives, which are present on all maps.

DI=destroy all the infected DS=destroy all swarms of infected DV=destroy all villages of doom

Swarm Missions

In these missions the Empire Points are used to buy units and defenses to save the Outpost. Units are available and upgraded depending on Technology research. These missions only reward Empire Points.

• Ranger: 10 EP (always available)
• Soldier: 20 EP (requires Assault Rifle)
• Sniper: 25 EP (requires Telescopic Sight)
• Lucifer: 180 EP (requires Mechanical Engineering)
• Thanatos: 240 EP (requires Mechanical Exoskeletons)
• Titan: 350 EP (requires Articulated Vehicles)
• Mutant: 1000 EP (requires Genetic Engineering)
• Wood Barrier: 10 EP (300 life, blocks single tile, always available)
• Wasp: 40 EP (300 life, blocks single tile, DPS: 100, requires Autonomous Wepaons)

Infected amounts depend on difficulty as follows: Easy 33%, Accessible 66%, Challenging 100%, Hard 110%, Brutal 125%, Nightmare 150%, Apocalypse 250%.
