Well if its like the last episode I would like to see an ending cutscene where your in first person but cant play and your just watching gorden waste all his bullets on every gun he has until he pulls out his crowbar and starts beating the crap out of the enemy (could be like a boss or a bunch of combines) then like it fades to black when he gets like shot in the chest.
But really I wanna see is more weapons (combine sniper, assault rifle, sword?) and a more enhanced garphics and maybe a remake of HL2 TDM but made better.
