Boomtown has revieewed the Firearms mod.

Here's a snippet:

With the main focus on the weapons and abilities, the mod is lacking when it comes to graphics. A lot of the models and maps can’t compare to the graphics we see today and it makes the game feel older to some extent. However, for a game designed with the Half-Life engine, there are some really cool things that shouldn’t be missed. There are a few good animations and the weapon models look real enough. Changing the mp5 to equip a silencer is probably the best looking animation I have seen. A lot of work has been put into the weapon models and animations and it has paid off. They look really authentic, not overly detailed, and they add to the excitement behind having a totally unique player.
