Ultra impressive in every way. 5/5 stars.

Without exaggeration, Cold Front might be one of the best custom campaigns ever made. This mod does everything a custom campaign can do to distinguish itself, plus extra things I didn't even know were possible. Snowy cities have never looked more gorgeous, the level design is well paced and easy to navigate, the difficulty is balanced, the Survivors are chatty, and there's a new melee weapon as a bonus.

What really puts this campaign above the rest is how fresh and new it feels. Metric tons of custom assets bring the wintery atmosphere to life. Programming wizardry has added the most advanced NPC in the game's history. The multiple endings are also genius — the finale starts as a gauntlet and ends as a holdout if you don't run fast enough.

I could gush for hours, but the bottom line is that anyone who likes L4D2 will love this campaign. The effort and creativity in Cold Front is staggering, and it's already one of the all-time greats. Just... wow!
