^^ More "desperate" sounding rather than "heroic" would be welcome for voice actors.
The american RS voice actor sounds like a spectator at a sporting event. Compare this with the some of the German voice actors in English who gasp for breath and heave as if they are tired, exhausted, and scared when speaking. This is a warzone. Let the voice actors reflect their weariness, sadness, and sullenness.
Tell your actors to sprint around the block several times then record.

One final note: Something about the player models in RS compared to RO2 never seemed quite right to me. The uniforms in RS seem too smooth and lack natural variation in shading.
Taking a look at this RS screenshot:
Compared with:
^^note this isn't just uniforms but the human skin as well; look at the hands

EDIT: To make it REALLY obvious. Look at the german uniforms in this screenshot vs the Japanese and American ones
If you look at the RO2 screenshot, uniforms, even new ones, have much more wrinkles and creases putting more darker patches on the character model. RS1 and RS2's models look a bit too bright without as many creases and wrinkles. It results in the uniform appearing to have just a single shade of color and thus seem out of place compared to the rest of the environment. While the uniforms themselves are produced with a single dye, when worn, many shades are visible due to lighting. It would be a good idea to revisit the bump maps for all models and objects to add more darker areas from folds and creases.
I mention this because I think its your biggest problem right now in terms of visuals and graphics. Its holding you back the most.
I hope others can see and acknowledge what I'm talking about from those pictures.

Edit #2: The guns in RS and RS2 also seem to have this "too smooth" thing as well but its not as bad. Something about the bump maps between RS and RO2 models seems a bit different. Revisiting the bump maps for a lot of things would go a long way to making the game look MUCH better.
