Frontline Protocol is a real-time strategy game with deckbuilding and auto-battler elements. You can expect a tactically dense card system. During each match, you have access to three selectable decks, rewarding specialization, deck planning, and player skill while allowing you to strategically control every frontline.

Whether playing solo or in online co-op with up to three other players, every battle brings new challenges. You share resources, spawners, and buildings. Through your deck composition, you can focus on specific roles:

Economy – Construct new buildings or upgrade existing ones to generate more resources for your team.

Defense – Build new towers or upgrade existing ones to stabilize your frontlines.

Support – Maintain battlefield awareness and react to the enemy to counter weaknesses in a targeted way.

Offense – Deploy troops to destroy enemy towers and capture the base.

Meta-Progression System

As you progress through the game, you earn Booster Credits, which can be used to purchase new booster packs. These contain new cards, temporary bonuses, and resources to further develop your decks.

Cards can also be upgraded, permanently reducing their deployment cost - creating long-term strategic depth instead of short-term optimization.

With every level up, you receive a skill point that can be freely invested into passive bonuses, such as increased starting resources, a larger starting hand, or improved resource income.

Unlock achievements to earn additional credits and open even more booster packs.

With over 300 cards for units, buildings, towers, and special actions, you have the freedom to discover and refine the playstyle that suits you best.
