Top Features

TEC Titans - The Ankylon and Ragnarov

The loyalist Ankylon titan can serve as the core of any combat fleet. The Ankylon features several abilities to augment both friendly and enemy forces:  Disruption Matrix is a powerful area ability that will damage enemies over time and prevent them from using abilities; Furious Defense great increases the Ankylon's weapon damage and repair systems; Shield Surge can instantly restore shield points to the Ankylon and to nearby friendly units; and Invulnerability Field super-charges the titan's shield emitters making all friendly ships within range invulnerable for a short time.

The rebel Ragnarov titan is a mobile weapons platform build entirely for offense. It's special abilities enhance it's massive railgun which spans half the ship's length:  Piercing Shot fires a powerful, long-range shell to deal massive damage to a single target; Explosive Shot fires a concussive blast shell at a target to deal AoE damage; Warpath grants the Ragnarov a stacking weapon damage bonus for a short duration; and Novalith Cannon fires a devastating nuclear payload at an adjacent hostile planet.

TEC Novalith Cannon

This deadly superweapon returns exclusive to the TEC Rebel faction, granting them incredible power. The Novalith Cannon is a powerful railgun developed through extensive research, capable of launching devastating Novalith Warheads at incredible speeds. These warheads cause massive damage to a planet's infrastructure, making the weapon a formidable force on the battlefield.

New Fleet System

The new Fleet System in Sins II allows players to create and customize their own war fleets of ships to command, providing a more personalized and strategic gameplay experience. Fleets can be easily managed and reinforced through a special build bar, which enables players to order new ships from nearby factories. This streamlined system ensures that players can efficiently expand and strengthen their fleets, adapting to the ever-changing dynamics of the battlefield.

Planet Updates

The latest update reintroduces constructor ships, planet elevators and orbital traffic. Constructor ships are back for building and expanding your empire, while planet elevators reflect the development of your planet. Plus, ships will now fly out of the factory when construction is completed. Gas giants also received a refresh for this update.
