Great

Even though the same map layout is reused, I still enjoyed playing through it without getting bored.

That said, even if the layout is reused, I think changing the arrow textures for each chapter would make navigation a lot clearer.

Here are a few things I noticed:

**M1:**
- The map seems to consider players as having left the saferoom right from the start of the intro, causing Special Infected to spawn. I think it would be better to extend the saferoom area to include the spot where the medkits are located.

**M2:**
- Bots don't enter the trailer before the horde event, so it would be better to make them gather inside.
- It would be helpful to place some ammo or weapons in the trailer before the horde event.

**M4:**
- The message "Gather all Survivors..." appears, but it's not clear where we're supposed to gather. Some clearer directions would be helpful.
- It would be nice to have some guidance when each training session ends or when the next one begins. Using "env_instructor_hint" to indicate where to go could be a good option.

**M5 (Finale):**
- The map feels a bit too dark, so adding a few more lights might help. The contrast is especially noticeable since M1–M4 were much brighter.
- Personally, I don't think the ending necessarily needed to be a "Sacrifice" scenario.

**Other:**
- Special Infected sometimes get stuck because they can't break down the building doors.

Wonderful remake

In the previous version, the maps were so large that it was sometimes difficult to figure out where to go. However, since v2.0, items have been scattered throughout the maps, making exploration much more rewarding. It feels like more than just a remaster, with plenty of unique touches that made the experience really enjoyable.

Here are a few minor bug reports and suggestions.

**Map 1:**
- The console gets flooded with the following error:
  `Material models/error/new light1 has bad reference count -44 when being bound`

**Map 3:**
- There's a mysterious instant-death area (trigger_hurt) at `Origin: -2756.5 4149 89.5`.

**Map 4 (Finale):**
- The stairs leading up to the final rescue helicopter should be made wider, as the survivor bots tend to get stuck there.
- Also, the bots don't enter the helicopter and instead try to move around the outside. This might be because the helicopter isn't properly recognized as a rescue area.

**Other:**
- It seems that the "Survivor Shoving" and "Melee Grunts" addons have been incorporated into the campaign. I think it would be better to leave these features optional for players. Both are well-known addons, and some players may already have them installed separately.
