The Fog Fall Series
With an eerie atmosphere and a great theme, The Fog Fall revolves around the Cuban Missile Crisis gone awry. You play as an unknown survivor of a nuclear holocaust, who lives in a strange bunker-like house. One day, your character wakes up and finds the house surrounded by a mysterious fog and an eerie adventure begins.
Fog Fall has a very creepy environment with many machine and code-based puzzles. It displays some of the best pencil artworks and has good ambient sounds. The game is frighteningly entertaining and creepy. The series is created by the renowned Mateusz Skutnik, creator of the Submachine series, Daymare town and Covert Front.
The second game of the Fog Fall series takes you to a strange place populated with soldiers, strange mutants and a few damaged vehicles. After escaping the shelter, you get trapped in an apocalyptic war zone. The game has some of the best inventory-based puzzles. Items acquired are collected and stored at the bottom of the screen. You just have to click an item to use and combine it with the items of your inventory.
Fog Fall 2 has a few quests, but provides a satisfying point-and-click adventure gaming experience. The graphic novel approach and the eerie ambient sound effects fit the scenario perfectly. The game is one of the visually impressive free online adventure games ever produced by any independent game developer.
Hotel Escape 2
Hotel Escape 2 is a free online room escape game that tests your sleuthing skills. You will have to to search for items and use them to escape from a posh hotel room. Using your mouse, you can navigate and obtain items easily. Pressing the space bar will open the inventory and you can use any item collected. The game's inventory-based puzzles are a bit difficult, so there's a lot of trial-and-error involved in solving any puzzle.
The Trapped series of games are short, but interesting titles. In the first, second and third game of the series, players have to solve puzzles, collect and combine items to escape the room. Every game has a nice intro, which can be skipped if you hate in-game cinematic.
The puzzles are odd and require your logic to get solved. Although the interface is based on mouse-clicks, you can use keyboard shortcuts to use an item.
The game is played on a first-person perspective, but the overall size of the game is very tiny. Don’t worry, there’s no complex pixel-hunting. You will have to explore every part of the locked room and collect objects. The first game is impressive, so are the second two games: Pursuit and Escape.
