'''Delta 4''' was a British software developer founded by [[Fergus McNeill]], writing and publishing [[interactive fiction]].<ref name="su45">{{cite journal|date=December 1985|title=Hit Squad|journal=Sinclair User |issue=45 |url=http://www.sincuser.f9.co.uk/045/htsquad.htm|access-date=2007-11-27|url-status=dead|archiveurl=https://web.archive.org/web/20070912124318/http://www.sincuser.f9.co.uk/045/htsquad.htm |archive-date=September 12, 2007}}</ref>

Delta 4 designed games between [[1984 in video games|1984]] and [[1992 in video games|1992]]. Some were self-published, others were released by [[CRL Group]], [[Piranha Software]], Silversoft, or On-Line Entertainment. Delta 4 were also credited with providing the code for Jonathan Nash's tape magazine ''[[Your Sinclair#YS2|YS2]]'' which was given away free with ''[[Your Sinclair]]'' magazine and published by [[Future plc|Future Publishing]].

== History ==
Delta 4 was formed by McNeill with a few friends whilst still at school. Their debut text adventure games were the ''Dragonstar'' trilogy ("...like ''[[Colossal Cave Adventure|Classic Adventure]]'' but without the interesting bits"<ref name="su45"/>) and two ''Holy Joystick'' comedy adventures, self-published in 1984. Gilsoft's ''[[The Quill (software)|The Quill]]'' was the design software.

Their first critical success was ''[[Bored of the Rings (video game)|Bored of the Rings]]'', inspired by the [[Bored of the Rings|''Harvard Lampoon'' novel of the same name]].<ref name="su45"/> Published in 1985, it received a ''[[Sinclair User]]'' Classic award.<ref>{{cite journal|date=July 1985|title=Adventure|journal=Sinclair User|issue=40|url=http://www.sincuser.f9.co.uk/040/advent.htm#bored |access-date=2007-11-27|quote=The humour can be fairly schoolboyish at times and there are a couple of occasions when it is both distasteful and unnecessarily unpleasant.

In the early 1990s, Delta 4 developed several CD-based games. ''[[The Town with No Name]]'', ''Psycho Killer'' and ''The Hound of the Baskervilles'' were all developed using D.U.N.E. (Developers Universal Non-programming Environment),<ref>{{cite web|title=D.U.N.E. (Developers Universal Non-programming Environment)|url=http://hol.abime.net/4314|website=Hall Of Light|access-date=12 December 2018}}</ref> and all games were panned by both critics and players.

''Psycho Killer'' is a [[Adventure game|graphic]] [[action-adventure game]] released by On-Line Entertainment in 1992 for the [[Commodore CDTV]].<ref name="mobygames cdtv">{{cite web|title=Psycho Killer Credits (CDTV)|url=https://www.mobygames.com/game/cdtv/psycho-killer/credits|website=MobyGames|publisher=Blue Flame Labs|access-date=28 October 2018}}</ref> A version for [[MS-DOS]] was released in 1993.<ref name="mobygames dos">{{cite web|title=Psycho Killer Credits (DOS)|url=https://www.mobygames.com/game/dos/psycho-killer/credits|website=MobyGames|publisher=Blue Flame Labs|access-date=28 October 2018}}</ref>

The game involves the protagonist (unnamed in game but listed in credits as "John Schulz") going on a quest in order to save a woman (listed as "Sarah Collins") from a murderer ("Morgan James"), and to save himself. The graphics for the game were created using digitised still photographs that were taken in the suburbs of [[London]].<ref name="format i32"/><ref name="format i39"/>

Gameplay of ''Psycho Killer'' is restricted to a point-and-click interface, such as clicking certain arrows to go their respective direction.<ref name="format i32"/> There are multiple times in the game where the player must respond promptly to a [[quick time event]] in order to proceed to the next scene. Failure to do so can result in the game ending with the protagonist's death.<ref name="format i32"/><ref name="format i39"/>

In issue 32 of ''[[Amiga Format]]'', the reviewer gave the game 13% and complained of "poor gameplay",<ref name="format i32">{{cite magazine|url=https://archive.org/details/Amiga_Format_Issue_032_1992-03_Future_Publishing_GB/page/n25|title=Psycho Killer|department=CD Games|magazine=[[Amiga Format]]|issue=32|page=27|date=March 1992}}</ref> comparing it to an "interactive home movie" and asked who would want to play a game featuring a "spotty herbert who drives a [[Vauxhall Chevette]]". The game was reviewed again in issue 39 of the same magazine; the review gave it the same score,<ref name="format i39">{{cite magazine|last=Noonan|first=Damien|date=October 1992|title=Psycho Killer|url=https://the-eye.eu/public/Books/computerarchive.org/amiga%20format/Amiga_Format_Issue_039_(1992-10).pdf#page=38|url-status=live |department=Amiga CD Titles|magazine=Amiga Format|issue=39|archive-url=https://web.archive.org/web/20190131042703/https://the-eye.eu/public/Books/computerarchive.org/amiga%20format/Amiga_Format_Issue_039_(1992-10).pdf#page=38|archive-date=January 31, 2019|pages=38, 41}} [https://archive.org/details/AmigaFormatIssue039199210_201901/page/n37 Alt URL]</ref> and complained again about the poor gameplay.

''Amiga Joker'' reviewed the game more positively. The magazine gave the game a 3/5,<ref name="joker">{{cite magazine|last1=Labiner|first1=Michael|last2=Löwenstein|first2=Richard|date=October 1991|title=Psycho Killer|url=https://archive.org/details/AmigaJoker199110/page/n57|magazine=Amiga Joker|pages=58, 59}}</ref> stating, "with a little bit of goodwill, the game could be described as a interactive movie". The magazine ended the review calling the game "the best pure CD game ever."

''Amiga Magazine'' also reviewed the game positively, but did not give a score. The magazine spoke about the "forgiving reaction time".<ref name="amiga magazine">{{cite magazine|last=van Rijn|first=Lawrence |date=January–February 1993|editor-last=van Die|editor-first=Jan|title=Psycho Killer|magazine=Amiga Magazine|issue=19|display-editors=etal|page=89}}</ref> The magazine also said that the game is well-tuned to the CDTV. The magazine complained that the mouse pointer was black which made it "impossible to see" during some scenes.
