I really hope this ends up being a big hit - Techland has made such an incredibly entertaining experience here.
I started a New Game Plus immediately after beating it the first time, and now I'm on a third play-through. The gunplay continues to be super-satisfying after over 10 hours.
The hit and death animations are excellent, the ragdoll feels heavy and weighty, and dust gets kicked up when bodies impact the ground, accompanied by a wonderfully exaggerated, meaty "thud" sound that makes enemies feel like they're 300 pounds of dead weight. All of the weapons feel and sound great; all are fun to use in different situations. The shotgun is the best since the original F.E.A.R.
The environments are surprisingly varied, and are supported by great design and layout - the levels just flow really well. Tons of fun encounters in interesting settings.
So much attention to detail; so many little extra touches: massive flocks of birds in the sky, idle weapon animations and cool "stylish" animations after final kills (twirling the revolvers, flipping the rifle forward, checking the shells in the shotgun), swarms of insects buzzing around swampy areas and dead bodies.
Load times are really short, so dying doesn't feel like punishment (on 360). Narrative dialog doesn't repeat when you die and have to replay a section - so many games should learn from this. You can choose between left trigger aiming down sights while dual wielding, or have each trigger fire each gun independently. Player-friendly touches like this are common.
The narrative hook works well, with lots of clever and humorous moments. The "tall tale" angle is perfect for the setting, and the growing skepticism of the listeners is played to great effect.
I know I'm really gushing here, but this is genuinely one of my favorite FPSs of the generation. I'd still be completely satisfied if I'd have paid a full $60 for this. Even if you don't like westerns, give this a shot if you are craving a FPS that is just plain fun as hell.
