1. Three young mercenaries trapped in dead-end jobs get the opportunity for one shot at fortune and glory, so long as they can avoid getting killed in the pursuit of a fragile and highly-prized collectible.
I like this one better too, I think because the protagonists are immediately identified, and the first verbal is strong ("trapped"). I would suggest trimming and intensifying that "Get the opportunity"-- maybe "risk all" or "gamble all"? Go for high stakes terms to show the urgency, and be wary of the stacked verbs (can avoid getting killed). Try " ... so long as they don't get killed pursuing a ..."
Also, if it's important, maybe say what the collectible is?
Good work-- just watch those "wriggle words" in your verb phrases.
