3rd ed was our first codex. There were no Wracks or Cronos back then.
Grotesques had no weapons or available upgrades. If they were not accompanied by a character they were subject to Stupidity (needed to pass a Ld test with their Ld 5 to move). They were T 3 with 2 Wounds, but were not effected by shooting attacks of less than S 6, though close combat worked normally (because you could "chop bits off them"). Opponents beaten by them in close combat had to fall back without a Ld test being taken.
Haemonculi didn't do much, since we didn't have Power from Pain back then, but they were cheap (25 points) and you could take 3 of them for a single HQ slot.
Talos had a gun that wasn't very good, (24", S 4, AP 5, Assault 6) that they had to shoot at the closest enemy models in range and line of sight, one shot per model, with any extra shots being wasted. They had an Attacks characteristic of D6.
