Honestly, it's not just the voice over. It reminds me of the emptiness of Half-life for some reason. It looks like a 1999 game with a 2015 visuals. They show generic characters standing and a car explosion. They show one man being beaten up by two people, over and over again. The trailer is scripted and flimsy like it's done in Garry's mod. They show a door being kicked into without any impact. They show a girl screaming who is not present, like the audio is added in later for dramatic effects. They show one guy on his knees. They show another guy on his knees. They show another guy on his knees, like it's suppose to make us feel emotions.
They show a guy with no emotions and dead eyes pointing a gun at you.
They show shitty quotes on a ridiculous font on the walls trying to make it look at dynamic. They show another car explosion with the same animation as the previous car explosion. They show empty streets being "liberated" by empty NPCs.
Don't get me wrong. It's great seeing in-game trailers for once in a while, but it shows that your single-player game has no cinematic moments that you have the confidence to show in the trailer, let alone use better camera angles or cuts or audio.
