A single-player story mode made to be the heart of Iron Harvest. Including all the factions, it is a story built from the ground up to be a homage to the campaigns of old. Besides playing it alone you can also play with a friend in coop.
There are different Challenge maps. For example, one of the challenges is a "Hold the line"-mode, where you fight as Polania against 10 waves of Saxony. Survive while building up an army and trying to capture new mines and pumps to strengthen your economy.
Games against the AI. The AI has the difficulty settings "Easy", "Medium", "Hard" and "Insane". All maps and features from the multiplayer are available in skirmishes.
Games against other players or with your friends. You can also play coop with others against the A.I. Play "Quickplay" if you want to play with random players and use "Create lobby" to invite friends.
Winning by Victory Points (VP)
The Capture of flags placed strategically on the map. These can be capped and decaptured with infantry and exoskeletons. By default, you will need 500 VP to win, but that can be changed or even disabled.
You will get 0.3 VP per second, per flag, you occupy more than your enemy.
As an extra feature, flags that have been captured will slowly accumulate up to 5 orbs. Each lit orb gives 10 bonus VP to the team that decaptures it.
In the mode Drop Zone you do not get points for capturing flags but instead picking up crates. The crates drop from time to time on specific locations and will provide 50 VP once picked up. The need VP do not change.
Winning by destroying the enemy’s HQ
The secondary win condition is attained through the destruction of the enemy Headquarters (HQ), but just like the last one, it can also be disabled. However, if disabled, the requirement becomes to kill all units as well as the HQ having to be destroyed before the game is won.
Note that the HQ can be rebuilt by engineers if destroyed. This can be extremely useful in a team match since all Headquarters of the enemy team need to be destroyed.
Iron and Oil are the two main resources in the game and are used to create all units. Luckily, they can be attained from many sources like the HQ, Iron/Oil nodes, crates, and even mech wrecks can all give you a various amount of the resource. Crates and wrecks serve as one-time income boosts, while the HQ and Iron/Oil nodes are generating resources for as long as you control them. Also note that resource gain is shared in 2v2 and 3v3.
Iron is the more prevalent resource and used in just about everything in-game. From infantry to mechs, and building upgrades, you are going to need iron the most if you are to succeed in battle.
Oil is the secondary resource that is used by buildings, mechs, and stronger infantry. It is paramount to get a steady source in the late game when oil becomes more heavily used.
The last Resource is army size. Units need available army size to be built and usually fill from 3 to 7 slots. By Default, you start with 20, but you can increase it by 5 by queuing a reserve. Each reserve gives you an additional 5. Building/upgrading the barracks & workshop also increases your army size.
Various things on the battlefield like Iron/Oil nodes, flags, crates, and even some weapon systems can be captured and used. Time is needed to capture said objectives and that can leave your units vulnerable to gunfire.
When capturing an object that was controlled by the enemy, there is also the added problem of being required to decap the enemy's flag on things like resource nodes and flags beforehand.
You can stop an enemy from capturing or reviving a hero by dealing damage to the squad, which is trying it. Still will take away from progress and can delay or stop the capture.
Upgrading a Building
You can upgrade most buildings by pressing F. Building upgrades can give you various things from more resources to better units and reserves. The late game usually requires you to upgrade into better units in later stages of building progression. But always be mindful of your resources so that the resources sunk into the upgrade weren't needed for unit defence instead.
