Foothold v1.1 - Persistent Dynamic Sandbox

In this persistent dynamic sandbox, your goal is to move through the map and capture all zones from the enemy.

As you capture some areas, you will unlock benefits for your coalition such as an AWACS, friendly air patrols, or new spawn positions. Beware as the enemy will also launch attacks to retake what was once theirs.

Update v1.1 released with new features: air support, currency, random events.

The goal is to capture all zones.

To capture a zone, first you need to destroy all enemy forces deployed there, in order to turn the zone neutral.

Neutral zones can be captured either by assisting friendly AI supply aircraft, which periodically spawn at friendly zones, to land at them, or airlifting one of the cargo items found in various zones.

Friendly zones can be upgraded with extra units to improve their defense using the same mechanics as capturing.

If a zone has a group that is missing units, a supply delivery will first restore that group. An upgrade will only occur if all existing groups are in good condition.

These rules are common to all zones, but some zones can provide special bonuses as well, like friendly air patrols, an AWACS, supplies, or unlock new spawn points.

The enemy AI will also launch attacks to recapture lost zones, air patrols to protect their airspace and supply deliveries to reinforce their defenses, so plan accordingly.

Feel free to use the map to get an idea of what is happening, and use the F10 radio menu to get a report about any of the zones.

As mentioned above, some spawns will be blocked until you capture the zone they are in. The name of the required zone can be found in the unit/group name on the spawn menu. Most flyable aircraft should be available, but feel free to edit or set-up any slot you would like in any of the zones. As long as the coalition of the slot is different from the coalition of the zone it starts in, it will be automatically blocked. Try to include the zone name in the name of any slots you add, so that players can tell what zone they need to capture for that slot to open up.

New Features:

Critical Objects:

Certain zones will have structures in them that are critical to their functioning. If all of these are destroyed, the zone gets disabled and will no longer provide any benefits. No side can capture it anymore and any remaining groups there will no longer be repairable.


You can now call in support to help you in your conquest.
Available items include:
- F-14 Fighter sweep that will attempt to engage any enemy fighters in the area
- F-4 CAS mission that you can direct to a specific enemy zone to attack ground units
- F-18C SEAD mission that you can direct to a specific enemy zone to attack SAM radars
- Cruise missile strike that you can launch on a specific zone
- Instant level up of a selected friendly zone
- JTAC that orbits a selected enemy zone and lases enemy unit

These support items can be bought using credits, which leads us to the next feature.


You will now be able to earn credits in several ways:
- Factory and the new Oil Fields zones will provide a steady stream of income to the controlling coalition.
- New Convoy zone will provide a one time credit bonus if liberated from enemy forces, reward will depend on number of surviving convoy members.
- All kills will earn the player a certain amount of credits depending of unit killed. These however will not be instantly added to the coalition account. You will need to land at a friendly zone to claim the accumulated credits. Ejecting will also claim 25% of these credits.
- Airlifting supplies to friendly zones.
- Successfully completing intercept and escort missions that happen at random times.

Credits are common for a coalition. The enemy coalition also earns credits that it uses for the next item on the feature list.

Random events:

The red coalition will use credits earned from controlling certain zones to call in its own support. Some of these will just be reinforcements, and some will trigger events that the players can complete for some extra credits. I'll leave it up to you to find out what these are.

Note on Persistence:
Persistence is also available in case you want to stop and resume the mission at a later time. The state is saved every minute, but only the color and number of upgrades of a zone are saved, meaning partially destroyed groups will respawn fully restored once the mission starts up again.

In order for persistence to work you will need to edit the following file in your DCS install directory: \Scripts\MissionScripting.lua

Edit the following section:
  require = nil
  loadlib = nil
to look like this:
  require = nil
  loadlib = nil

To reset the persistence and play the mission again from the start, delete the foothold_1.1.lua found in the DCS install directory.

Note for running this on dedicated servers:
For the slot blocking to work, you will need to copy the slotblock.lua file into the savegames folder on the server under Scripts/Hooks and restart the server.
