We are planning to officially announce the games existence next E3 in a year. However, even though I'm risking everything doing this, I feel like I must warn you that this will not be the continuation you imagined.
The writers of Half-Life 3 have decided the story needed to update with times and match today's standards of incursion. As you may remember HLep2 ended with Alex crying over her fathers courps after getting killed by a psychic bee. The game takes off 5 years latter with Gordon Freeman completely gone from the story. Instead you will finish the trilogy as Alex Vans.
Now the ne writers weren't a big fan of how Alex was handled in the other games. So this time, they are focusing on making sure the player that Alex is STRONG and beautiful. In fact, she is the strongest soldier in Black Masas #Resitance against the forces of the Columbine regime.
There is scean much like the infamous can scean from 2 where a Columbin solder call her a dirty ni- you know... that word. You get a choice to either ingnore him or cut his dick off.
Also Alex, having forgotten Gordon... had found new love in with her latina muslim girlfriend. Over the course of the game there will be manny touching and romantic moments between these two as they overcome adversity with there diversity.
Anyways, I just thought I'd leak this to you guys because hey, if the FBI doesn't give a shit, I might as well become a leader myself. Anyway remember not to be shocked at the direction we decided to take the final long awaited conclusion to Half-Life.
