Welcome to the Line War Wiki

With the exception of the offline sandbox mode where you can play around as much as you want, Line War is currently a PvP multiplayer-only RTS game. This wiki will grow over time and act as the official manual for the game. The developers will contribute with confirmed official information, and the community is welcome to update this Wiki and add content and new sections to help out new as well as experienced players.

Units

This section describes the units found in Line War, where they are produced, and their properties such as health, speed, cost, energy consumption, weapons damage, and conquering efficiency. their stealth.

The Stealth column indicates whether a unit has a stealthy profile, i.e. even where the fog-of-war has cleared the unit may remain undetected by the enemy unless they have accumulated enough sight through multiple units or through recon units.

The Recon column indicates whether a unit has increased sight which may clear the fog-of-war and if the unit contributes to the sight so that stealthy units are more easily discovered.

A unit (u) is a measurement of distance in the game. For reference, the world map is approximately 200 units wide and 140 units tall.

Picking Phase

At the start of the game you can spent some time to pick your first zone. If your opponent picked his first zone nearby the zones will cancel out (red lines).
Then you pick another starting zone. Pay attention because a countdowntimer may start every moment in which case you have to select the other zones that you want.
They should be directly connected to another zone. You can select up to 6 starting zones and that is almost always the best choice.
Starting with less zones grants you 200 extra capital, but it is in general best to start with the largest income and the largest starting army. The larger your starting army, the faster you will conquer more zones and gain even more economy later on.

Tips for the picking fase:

1. The first zone you pick should be somewhere in the middle of all income sources, but also close enough to oil, since oil is so much cheaper then solar panels.

2. Be careful about picking zones in the corners of the map, your opponent can put you in lockdown. This is also, why the middle is a strong starting point.

3. Be careful about picking zones in the corners or borders of islands or larger continents. Your opponent may zone you out from conquering the rest of the island/continent.

4. Pay attention to the countdown timer, keep clicking until you have maxed out on the zones you can select. It was already stated, but you can simply lose the game by not picking the zones you need.

5. If your opponent owns the zone you clicked on, it flashes and you can't pick it. You now know that your opponent started close nearby.

6. If you know for sure where your opponent is going to start, you can try to counter that, but it is risky. More on that later.

7. You can click through a waterzone and select a landzone on the other side of the water. It comes at a cost of 4 infantry, that will not be placed. Make sure the waterzone is connected with a large enough boundary or it may not work.

8. On landmaps: conquering zones is probably better. On watermaps it may be better to start close to industry, villages and cities, since there aren't as much landzones to conquer.

9. Try to pick zones such that they are close to each other rather then a chain of 6 zones. Otherwise you risk that some of your starting zones can be easily attacked by your opponent with overwhelming force.

Why are starting spots so important?
The nearest neighbor principle shows us who has a better sphere of influence on the map.

At the start of the game both players pick their starting points. From a mathematical standpoint

there is a logical way to determine which starting point is better. Here is the picture of the nearest neighbor principle:

Here is an explanation of what you can do to estimate which starting point was better:

1. First you draw both starting points on the map

2. Then you estimate the middle point of the starting zones of each player

3. Then you draw line between middle points

4. Go to the middle of that line and draw a line on a 90 degree angle.

5. This line is just as far as from player 1 as from player 2.

6. Theory: by using this line you can immediately see, which player has a better starting point from a conquering perspective.

This has a large influence on who gets the best economy in mid-game, when both players conquered almost all neutral zones on the map. You can spot it from the start, but you can change the outcome by changing producer placement on the map, which shifts the balance of power.

Strategies

Longterm tip for studying the game:

Use Sandbox to test every unit under multiple conditions from tiny battles to larger battles. The reason is to find small hidden gems like: 2 infantry actually take out 1 unprotected artillery in the open field without losing a single infantry. The same is the case for infantry vs SAM.
Both situations are very profitable, but completely different stories at a larger scale ofcourse. Another interesting thing is to test all potential starting builds against eachother on multiple types of maps.

You should usually start with 6 zones with 4 infantry in each zone. There are some exceptions on watermaps if you like to pick a water zone for either oil or clicking through towards another island.

Tips for the first minutes of the game:

1. If one of your opponent's zones are directly linked to 2 or more zones of you, without any backup nearby, make sure to attack with 8 vs 4 infantry (or better 12 vs 4).
Kill them with overwhelming force and grab the zone (-12 income for your opponent and +12 income for you as well as an advantage in infantry numbers).
If you are on the unlucky side of such exchange, make sure you don't lose your starting infantry to overwhelming force, you wil lose that specific zone anyway.
2. Immediately make your buildings in the first 10 seconds. The quicker you build them the more you will be ahead in production. There is no way to scout and counter your opponent right now, unless you want to miss minutes of production.
3. If you don't know what to do on a land map, but you expect your opponent to be somewhat close: build 3 factories first (with 1000 instant build budget) and some barracks followed by an oil refinery ASAP. Then follow up with some tanks, maybe some defensive SAMs to defend your oil. It is hard to lose with that in the early game on land maps.
4. If you don't know what to do on water maps it is usually a good idea to make an airfield with some strikers and a shipyard with 1 troopship and missileships, unless there is a real chance your opponent started on the same large island as you, then ships may not help as much. You can choose any producer as your third building.
5. Usually don't start with tanks on water maps, they can not be shipped in troopships, unless you own a zone at the other side of the water. Sometimes an early tank-surprise on water maps can not be beaten though.
6. Always start conquering as soon as possible with your starting infantry.
7. Use your infantry for conquering zones and your other units to defend your base or to attack.
8. The most likely way to lose in the early game is against tanks or strikers if they start popping unprotected buildings. Best way to defend against both strategies is to take out your opponents oil refinery.
You can also take down the airfield with tanks and kill the strikers in the proces. You need 2 flights with a striker to kill 1 tank (tank hp: 210, striker damage per flight: 140).
And tanks build faster then strikers, so you have more of tanks than can be shot down in one flight. This means that it is hard to shoot down the tanks before they drive into the base and start shooting down buildings. Currently the sweet spot seems to be 6 tanks driving towards your opponent's base around the 2:30 minute mark.
If your opponent uses all of his infantry to defend his base, that is also perfect for you, because your infantry is still conquering zones, which will put you ahead.
9. The quickest way to demolish your opponent's oil refinery on any given map and starting distance is probably the commando airdrop instant build: 2 barracks-commando + airfield-transport-jet.
It takes 87 seconds until you are able to fly towards the goal and most often it can not be countered, because it only takes 30 seconds to shoot down the refinery with 2 commando's.
Risk: 2x30 + 60= 120 capital and potential reward: 264 and oil starvation of your opponent as well as infinite annoyance and rage quit potential.
10. Starting with too many economic buildings can be very unsafe.
11. Try to find the best spots on the map to build a second or third base. It gives more map control than having one single big base.

Tips for the mid game:
Mid-game happens around the time that both players are about to conquer the entire map. This is the moment where you should ask yourself the following questions:
1. Do i keep attacking or am i better of defending and wait while planning my next attack? There are situations inwhich attacking is just to risky and the same may be the case for your opponent.
2. Do i need to boom my economy with cities villages, harbours etc? Sometimes you can win the game right away by pushing your advantages.
Why wait and spent 2400 on 2 cities first, while you already have 500 cashflow per minute and are on the winning hand? In such case making more military buildings or a rocket can be much better.
3. Do i need a rocket? This 1000+ capital question is really important, because it can be the pathway to victory. For instance if your opponent build 5 buildings to close to each other.
In such case you should always think about using a rocket, especially if there are good second and third targets as well. Rockets are also great for cleaning up the beach before starting your landing with troopships.
4. Where would my opponent build a rocket if he was going for one? Where should you scout with an interceptor? You can do as if you build a rocket on your opponent's beach,just to look for the most optimal and safe locations for him to put his rocket as well as the range of the rocket and which places he could potentially attack.
5. Where are the weakest points in my defense right now? A good defense can be more profitable than attacking. Focus especially on SAM placements.

How to land on your opponent's side of the water in mid to late game:
1. You should own the water or at least be reasonably safe with your fleet at the spot where you want to land.
2. You should have enough troopships. The longer the distance, the more troopships you need, Somewhere between 4 and 8 should be decent.
3. You should have a large army ready to be moved.
4. You should have a lot of energy and energy income and a decent amount of capital to quickly build multiple military buildings on the other side of the water.
5. Rockets are perfect for destroying your opponent's defenses before starting your landing. Drop the rocket slightly before their army, or risk losing the rocket to AA.
6. After the rocket, follow up with your air units and push your cruisers towards the beach where you are going to land.
7. Make sure to move SAMs and missile ships to defend your landing troops and troopships.
8. Often it is a good idea to do multiple attacks on other places on the map at the same time. For instance some annoying commando drops to keep the enemy busy.
9. Watch out for counter attacks. Your opponent could try to shoot down a city with commando's while you aren't paying attention, make sure to watch the entire map.
10. The ultimate defense your opponent could use is a rocket. To shoot down your landing troops and troopships. Often it is best to land a lot of your SAMs first.
