Ive just started playing DOD: Source. I thought it sucked, and never gave it a try (due to DOD1) It came with CSS, so I checked it out. It is quite fun and well made. The feel of the guns fire, recoil, and unique gameplay aspects make it enjoyable and different. HDR and Dynamic Tone mapping make it stunning to look at! The map design is excellent, as with the models. Its very addicting! I want to promote this game to others so they can see how fun and great it is
Give it an hour or two and you will get a pretty full idea of its gameplay.
