There will be closed testing of new mechanics and consumables for a new possible game mode:
Fuel Smoke consumable. By injecting fuel into the smoke stack the ship is covered by the smoke screen, but for the less time than using Smoke Generator. This consumable allows the ship to move at full speed and still be in the smoke screen;
Smoke Shells consumable, which allows setting smoke screens at range by main caliber guns;
Semi-armor-piercing shells - a new type of shells, which has high damage and low armor penetration. Like armor-piercing shells, these new shells can't start the fire;
Near-shore concealment - ship ability, lowering her detection range near the shores. The ability is activated automatically if the ship is not moving or moves at low speed.
These are early prototypes and their names, parameters and properties may change during testing.
Please note that the information in the Development Blog is preliminary.
