Spectrum Computing
Warlord (credits, magazine scores, compilations and the published solution).
Celts Against Rome
Sinclair User set the scene: Vespasian's legions have fought their way up to the Scottish border, where they are stopped by a tribe led by you, the warlord. The gods agree to settle the war by single combat: you and a Roman centurion are sent into a Celtic Otherworld, and the first back to the real world wins. See the reviews.
Solved Without Knowing
Computer & Video Games noticed that the game lets you solve a puzzle without telling you. The first time through the enchanted wood the path was easy, but without the staff "some very strange things began to happen". See the reviews.
No Tying
Sinclair User found it odd that the game didn't understand "tie" while you were holding a rope, although the game does have the message "You've nothing to tie him with." at Messaging_YouveNothingToTieHimWith, which is printed only if you capture the Roman without the rope (Process_CaptureRoman). See the reviews.
The Guild
Warlord was reissued on The Guild compilation in 1986 with Border Harrier and The Golden Cobra, and later on the Your Sinclair issue 48 Smash Tape Special Edition. Your Sinclair issue 53 printed a solution. Source: Spectrum Computing.
The Last Ring
Stepping into a ring is handled at Process_StepIntoRing. In the Crystal Cavern it takes you to room 57; anywhere else it takes you to room 43, unless bit 5 of Flag_QuestProgress is set, in which case it takes you to room 56, which is the end of the game, written as a room description. That bit is set when the urn is thrown into the fire at Process_ThrowUrnIntoFire, which also kills the Fomorian tribe.
A Spare Staff
The routine at Process_GetStaff_Duplicate does the same as the "get staff" code at Process_GetStaff (the same exit changes, in a different order) and is never used.
Get Or Take
Warlord's vocabulary at Table_Vocabulary accepts GET as well as TAKE. Its successor After Shock only knows TAKE, which several reviewers complained about.
Don't Be Disgusting
Token 25 (19) in the vocabulary, at E15B, holds four words, stored as "FUCK", "SCRE", "RAPE" and "STUF" (the game only keeps the first four letters, so SCRE is SCREW and STUF is STUFF). Use one of them on something and Action_Swearing answers with a flat "Don't be disgusting." (Messaging_DontBeDisgusting). Unlike The Jewels Of Babylon, it doesn't keep count.
