Based on player feedback, I have made the decision to move the Build Barricade action to its own... action... as opposed to being part of Interact. It was too confusing, particularly when trying to rescue coworkers. Starting with this release, the Y button on a Xbox controller, or the Q button on your keyboard, will build a barricade. Other Interactions remain unchanged.
Level 1 also features a new melee weapon, the cutting blade from a guillotine paper cutter! It swings very swiftly, and if you can time it properly it will kill a zombie in one swipe.
Have fun, and thanks for playing!
