Retro FPS Kit - Complete Template

Asset description

Playable Demo (Windows) | Documentation | Video Tutorials | Trailer Retro FPS Kit is a game template inspired by classic first-person shooters like Wolfenstein and Doom. 🔥 Latest Highlights: Modified the ammo system: ammo is now a regular inventory item, and weapons draw ammo directly from the inventory when reloading Ammo can now be picked up without owning the corresponding weapon The weapon ammo counter now shows the total number of rounds across all ammo stacks in the inventory Picking up a duplicate weapon now converts its loaded magazine into inventory ammo Added an Allow Multiple Stacks toggle to the item configuration (ItemSO ScriptableObject). When enabled, picking up an item whose current stack is full creates a new stack in another available slot instead of blocking the pickup. When disabled, the item cannot be picked up once the stack limit is reached The stack counter (e.g. (1/4)) is now displayed from the first pickup.
