I'm thinking a death of Hicks scene would be similar to a certain fellow getting his brains bashed in issue 100 of Walking Dead if anyone is familiar with that panel lol.
Or big twist. Ripley gets her skull renovated and Hicks now fills her role of being a leader, evading rape, and a sacrifice. Hicks takes Bishop II into the lead with him ala Purvis in AR. The queen burster rips through both of them as they fall. Bishop II gets the sample he wanted. Hicks whispers "Ooohrah to ashes" into his ears as the molten metal engulfs them. Turk arrives at that fateful moment, collapsing to his knees as WY Mercs close in.
Fast forward to 2013 (our new Alien 3 changed the future) and A:CM releases to critical praise (O'Neal dies in mission 1). Turk becomes as popular as Master Chief and we get yearly A:CM releases and everybody but AVPgalaxy bitches about too many Alien games saturating the market. Everything is copacetic.
I've never really speculated on the what ifs too much, but it's an entertaining exercise lol. Hicks saying Oorrah to ashes is actually the worst possible scenario imaginable.
