Catloaf 2600 is a small, minimalist, retro-style type of game. You are Catloaf. Through mysterious means, the nemesis foe, Master Meatloaf, has planted you inside his twisted creation, a labyrinth of puzzles and traps. 
 
The goal is to find your way through the maze and to Master Meatloaf himself, who is waiting at the end. The path is blocked by a series of puzzles. Find keys to unlock doors, push secret walls to reveal new rooms, move a boulder down a corridor to complete a sokaban-style puzzle, and memorize the path around traps before the lights go out. Switches shift the walls of the maze to reveal new paths and secrets. The graphics are drawn with all ASCII characters. You use the keyboard to navigate.

Cataclysm: Dark Days Ahead (aka Cataclysm DDA or CataDDA) is an open source survival horror roguelike set in a post-apocalyptic and fictional New England.

Unlike most roguelikes, it has no goal: the player is free to explore the procedurally generated map, clear areas of monsters, work with NPCs, and build shelters and vehicles. The gameplay is mainly based on day-to-day survival, and the game tracks parameters like hunger, thirst, morale, illness and temperature which the player must manage to stay alive. Like most roguelikes Cataclysm: DDA follows turn based gameplay.

The world has support for seasons and dynamic weather conditions and the season lengths can be modified during world generation. A typical world has cities, towns, rivers, forests, bridges and other landmarks. Cities and towns generally have all the common establishments generally found in real world such as houses, departmental stores, malls, parking lots, swimming pools, hospitals, malls, etc. Exotic locations such as Science Labs, Military installations, missile silos can be found in remote places throughout the whole world. Latest versions have support for experimental 3-D buildings.
