Stonekeep is a first-person RPG in the style of Eye of the Beholder and Dungeon Master. The game is set in a series of underground labyrinths, filled with monsters, treasures and traps. The player uses the directional keys on the keyboard for movement and typing in notes in the journal and uses the mouse pointer to interact with objects and characters. The mouse pointer is usually a target indicator for aiming attacks and weapons wherever it is clicked. When the mouse pointer is moved onto a particular something it changes to another icon to indicate a different action. For example, the mouse pointer changes to an eye when the player can examine things (often signs) or the mouse pointer changes into a spread-out hand when the player can pick up items. Other mouse pointers include opening and closing chests, opening and closing panels, pulling levers and switches, pressing buttons, drinking water and giving items.

​The protagonist Drake has two starting possessions: the magic scroll and the magic mirror. The magic scroll allows the player to pick up an infinite number of items. Items of the same type can be combined together up to a maximum quantity of 99; other items can be combined together such as a quiver which can hold 99 arrows. The magic mirror allows the player to equip Drake and other characters with weapons, armour and accessories and to consume items to affect their status such as healing potions or bad smelling Throg food otherwise Drake can read scrolls used on him. Although Drake can wield any weapon, other characters like Farli and Karzak can only wield hammers, axes and shields. Certain weapons like polearms and heavy swords require Drake to have two free hands to wield one. Some armour can be worn by certain characters. For instance only dwarves can wear dwarven platemail and only Drake can wear knight armour. Exceptional characters like Sparkle and Wahooka cannot be outfitted, but can still consume items

​The third possession is the journal available once the player procures it. The journal is divided into six sections. The first section of the journal records the statistics of Drake, shows the status of his current equipped weapons and describes the characteristics of his partners. Drake statistics are strength, agility, health and his weaponry skills including polearm, sword, magick, missiles and others. The second section of the journal records any clues and hints the player may come across. The third section of the journal is used for writing notes. The fourth section of the journal records items each time the player picks up a new type. The fifth section of the journal records runes each time the player comes across a new one. Unlike the items section, the runes do not have their own respective name recorded. The sixth section of the journal records the level maps that the players journeys through. Spots on the map can be clicked and notes referring to them can be written.

​Stonekeep features an elaborate 'Magick' system where four types of runes are inscribed onto a spellcaster (wand): Mannish, Fae, Throggish, and Meta. The first three runes are used for offensive, defensive and special interaction purposes. The Meta runes enhance the effectiveness of the base runes, like double power multiplies a single firebolt in two. To use a spellcaster, it must contain adequate mana and runes must inscribed onto the shaft of the spellcaster. To inscribe runes on the spellcaster, the player needs to equip the spellcaster on either one of Drake's hands, open the journal onto the Runes section, take out the spellcaster and copy the runes onto the spell slots of the spellcaster. Then the runecaster can be taken out at any time and the spell that can be used has the spell slot highlighted and launched on the indicated target point. Using the magic mirror, some spells can be aimed on the characters especially healing and quickness spells.

System Shock 2 is a first-person action role-playing horror video game for Microsoft Windows, OS X, and Linux released in 1999

​
​Originally intended to be a standalone title, its story was changed during production into a sequel to the 1994 PC game System Shock. The alterations were made when Electronic Arts—who owned the System Shock franchise rights—signed on as publisher. The game takes place on board a starship in a cyberpunk depiction of 2114. The player assumes the role of a soldier trying to stem the outbreak of a genetic infection that has devastated the ship. Like System Shock, gameplay consists of combat and exploration. It incorporates role-playing system elements, in which the player can develop skills and traits, such as hacking and psionic abilities.

​System Shock 2 received positive reviews but failed to meet commercial sales expectations. Many critics later determined that the game was highly influential in subsequent game design, particularly on first-person shooters, and considered it far ahead of its time. It has been included in several "greatest games of all time" lists. In 2007, Irrational Games released a spiritual successor to the System Shock series, titled BioShock, to critical acclaim and strong sales. System Shock 2 had been in intellectual property limbo following the closure of Looking Glass Studios. Night Dive Studios were able to secure the rights to the game and System Shock franchise in 2013 to release an updated version of System Shock 2 for modern personal computers. OtherSide Entertainment announced in December 2015 that they have been licensed the rights from Night Dive Studios to produce a sequel, System Shock 3.

​The player takes the role of Kirt, a human with powers of shapeshifting. Among other forms, Kirt can become a huge cat-like animal, a floating tentacle-wielding gazer, and a dragon. In the beginning of the game Kirt finds out that he is not in fact human, but comes from a parallel world where there was a war raging between shapeshifters for centuries. Kirt, and his grandfather, are the last of their kind, and now the evil ones have found them. Kirt's grandfather opens a portal back to the homeworld, and that is where the story begins. Kirt's mission is to stop the demons once and for all, but first he will need to awaken his innate shapeshifting powers, which is where the obelisks come into play. Going up to one of these and touching it will unlock a new form, and the first is the cat form.
