Among the many references and inspirations in theXCOMfranchise, few are as intriguing to longtime fans as the subtle nod to ‘Terror from the Deep’ inXCOM 2. Originally released in 1995,X-COM: Terror from the Deepwas the second game in the classic series, famous for its underwater combat and horrifying alien designs. WhileXCOM 2takes a different narrative path, it still contains elements and echoes that bring back the chilling atmosphere of its predecessor. This topic explores how ‘Terror from the Deep’ has influencedXCOM 2and what players can uncover in terms of lore, gameplay similarities, and thematic crossovers.
The Legacy of Terror from the Deep
A Different Kind of Threat
In the originalTerror from the Deep, players battled aquatic alien invaders who emerged from the oceans following the events of the firstX-COM: UFO Defense. The game was known for its difficult missions, claustrophobic environments, and grotesque enemy designs such as the Lobstermen and Deep Ones. The tone was darker, and the underwater maps forced new tactical considerations like limited movement and vision range.
From Ocean to Earth
WhileXCOM 2does not include underwater missions, the developers at Firaxis have included thematic callbacks toTerror from the Deep. This is particularly evident in the War of the Chosen DLC, where players can encounter elements that feel inspired by the old oceanic nightmares. These references are subtle but meaningful to fans who are familiar with the series’ deeper lore.
In-Game References and Easter Eggs
The Avenger and Old Tech
One of the clearest links between the two games is in the design of the Avenger, XCOM’s mobile base inXCOM 2. The Avenger itself is a reimagining of old XCOM technology, salvaged and reengineered to fight the new alien regime. Though not underwater, this emphasis on retrofitted and recovered gear is reminiscent of how the original X-COM rebuilt its strategy after alien dominance from the seas inTerror from the Deep.
Enemy Designs and Muton Evolution
Certain enemies inXCOM 2, especially those with aquatic or amphibious designs, may remind players ofTerror from the Deep‘s grotesque creatures. While not direct copies, the design language used in the ADVENT forces and alien enemies carries some visual elements slimy textures, tentacle-like features, and aquatic coloration that evoke the horror-themed style of the classic game.
The Codex and Elders’ Origins
InXCOM 2, the Codex and Elders are hinted to be ancient and possibly otherworldly beings who manipulated life on Earth. This concept has similarities with the alien storyline fromTerror from the Deep, where ancient aquatic creatures had been hidden beneath the ocean for centuries. Although the games are not directly connected canonically, the mystery of ancient alien civilizations underlines both titles.
Conceptual Parallels in Gameplay
Environmental Danger and Tactical Pressure
One of the defining traits ofTerror from the Deepwas its punishing mission environments. Tight corridors, dark waters, and limited mobility created a strong sense of tension.XCOM 2mirrors this with timed missions, concealed enemies, and unpredictable ambushes. While you don’t dive underwater inXCOM 2, the feeling of being under pressure is ever-present, keeping players constantly on edge.
Resource Scarcity and Risk Management
Both games emphasize survival under dire circumstances. InTerror from the Deep, players struggled with low funds and frequent soldier losses. Similarly, inXCOM 2, especially in Ironman mode, every decision matters. You have to manage soldiers, prioritize upgrades, and make painful trade-offs. The survival theme that definedTerror from the Deepcontinues in the modern game with a different setting but similar weight.
Aliens That Evolve with You
In both games, aliens don’t remain static. As you progress inXCOM 2, enemies gain new abilities and defenses, forcing you to continually adapt. This is reminiscent of howTerror from the Deepintroduced stronger enemies and new mutations over time, keeping the experience fresh and challenging throughout the campaign.
Is a Direct Sequel or Underwater Expansion Possible?
What Players Are Hoping For
Given how iconicTerror from the Deepwas, many fans have speculated or hoped that Firaxis might revisit the underwater theme in a future expansion or sequel. The idea of XCOM agents diving into alien-infested oceans with modified weapons and underwater armor sounds both nostalgic and fresh. WhileXCOM 2andWar of the Chosendidn’t go in that direction, the door remains open for future installments to explore this setting.
Modding Community’s Role
Several modders have attempted to bring the aquatic horror ofTerror from the DeepintoXCOM 2using custom missions, enemy types, and terrain features. Although these projects are unofficial and vary in complexity, they show that there is continued interest in exploring themes from the older titles. Some mods include map types with flooded terrain, restricted vision, or enemies with oceanic themes.
The Narrative Connection Between Games
A Nonlinear Timeline
There’s no confirmed direct timeline connection betweenXCOM 2andTerror from the Deep, but the two share thematic DNA. One theory is that the events ofTerror from the Deepcould happen afterXCOM 2, in a post-victory timeline where remnants of alien influence still lurk beneath the seas. The narrative of long-dormant alien forces awakening mirrors what the Elders did on land inXCOM 2.
Shared Themes of Hidden Menace
Both games revolve around the concept of hidden danger. InTerror from the Deep, the ocean conceals monstrous creatures waiting to strike. InXCOM 2, the aliens hide in plain sight behind ADVENT’s facade. This shared approach to storytelling emphasizes humanity’s vulnerability to manipulation and surprise, deepening the horror aspect in both entries.
A Spiritual Successor
Even thoughXCOM 2doesn’t include literal underwater missions likeTerror from the Deep, the influence of the older title is evident in many aspects of the game. From subtle design choices and eerie alien aesthetics to gameplay pressure and environmental hazards, the legacy ofTerror from the Deepis alive and well. Whether you’re a longtime fan of the franchise or a newcomer looking to explore its roots, recognizing these parallels adds another layer of appreciation to theXCOM 2experience. With strong community interest and an enduring love for deep strategy and horror themes, it’s possible that we’ll one day see a true return to the dark depths where it all began.
