About IS Defense
IS Defense drops players into a fictional 2020 where ISIS has seized Northern Africa and is launching a massive invasion across the Mediterranean. You assume the role of a NATO machine‑gun operator tasked with holding the European shoreline.

01 / THE GUIDE
Story premise
The game imagines a world where ISIS expanded unchecked, conquering Northern Africa and threatening Europe via the Mediterranean. This alternate 2020 sets a stark backdrop for the player's defensive mission.

- Focus on the narrative context to enhance immersion.
- Compare the setting to classic arcade defense scenarios for perspective.

- Observe how each weapon handles different enemy types.
