Missing editors? I must be missing something here Kyth since the Strategy First and the Gamergate versions both have the mission editors, it's listed in the games features at both sites. Now if you mean the editors are there but not showing up the SFK42 game drop down boxes that's nothing new. Some owners of the original Lighthouse digital download version sold at Gamersgate had the same problem way back in the day
.
Side note: Steel Armor is on sale at Gamersgate for less then $7.00 USD ($6.80 I think).
Cheers
