Valhalla Classics is an episodic remake of the classic Amiga games Valhalla and the Lord of Infinity, Valhalla and the Fortress of Eve, and Valhalla: Before the War. Each game was divided into four episodes (overall twelve) which can be bought and played separately from each other. Improvements to the original games are new graphics, music, and voice recordings.
The Gallery is the third episode of the Before the War timeline which is a prequel to the first four episodes. Here the player takes the role of the Lord of Infinity who wants to kill his brother, King Garamond, to become king himself. In this episode, the player is in the castle's gallery where he has to solve many mysteries to find the hidden exit to the Royal Chambers.
The game is an adventure in top-down perspective. The player walks through the maps, talks to people and solves puzzles which are either logic, inventory, or dialogue based. To interact with his surroundings the player has to walk in front of the object and person and then needs to press one of the three action buttons (look, operate or take). The inventory is limited to ten objects and the player can hurt himself. When the stamina bar reaches zero he dies - but it can be replenished by potions.
