I found the file to be a good, though rather short, depiction of a foreign invasion. The scenario was kept simple and (as dragonslayermcmx pointed out earlier) the scenario lacks soundeffects and music. It is my opinion that such extras would only add to the atmosphere. Overall I enjoyed watching the cinematic.
The transition between the different scenes could have been smoother. At a certain point the game showed a burning, supposedly pillaged, village without any looters. It took the barbarians some time to actually show up and start their fight with the guards.
The author used Player One as the owner of units and buildings coming under attack. This was very distracting.
Although a similar background story has been used countless times already, I found it quite well executed. The scenario showed a couple of battles, most of which were entertaining to watch.
Map Design: 3
The overall map design was bland and could really use some more detail. Large patches of 'Grass 1' gave me the feeling that the file was far from finished.
The instructions showed a quick introduction which was an interesting read. It made me quite curious about the rest of the scenario.
It also showed some basic information about the preferred settings, which were a bit confusing. Both the gameplay speed and the resolution should be set to 'normal'. As the native resolution differs for most users, I found this lacking detail. An exact resolution would have been better.
Waves of Carnage is an excellent start for a project. I look forward to seeing more of your work in the future.
