The Attack on Calzean is actually a fast paced invasion map not a siege. Standard work for this author, this map fits in with this series of four submits and has much of the same design features.
Playability 2/5 the three enemy invasions are no match and are quickly turned into chopped liver by the defending ballistic troops. Game play is smooth and the AI puts out a good effort at taking the castle. The massive number of archers and bowmen atop the castle walls however, render that effort hopeless. The author has each wave come from a different side of the map. This is a good idea but with such a force of archers all you have to do is move them from one side to the other and its over in seconds. Finally the siege will not end. The author needs to make adjustments to the victory conditions. There are a lot of errors in this category and I hate to give such a low score but this map has some real problems.
Balance 3/5 as stated above the defending troop combination is far too reliant on ballistics and destroys any challenge this map might have had. The attacking troops are very well balanced and it is a shame that this force never has a chance. Pitch and kill pits are very well used on this map and it is nice to see such sensible placement for a change.
Creativity 3/5 A better effort here than in Castle of the Hills. Slightly above average but more effort and ideas are required for a higher score. Huge bonfire is a nice touch but what is the point? There is no explanation or incorporation of this idea into the storyline. IMO it would have been better if such a dramatic feature had a reason.
Map Design 4/5 Calzean castle is very well designed and a lot of effort has gone into creating a formidable and functional fortress. Access points are limited and if the enemy invasions had a chance this would be a good defensive aspect of the map. The surrounding terrain shows a solid effort at creating an interesting and attractive landscape. The waterfall/rapids have a bizarre rather unrealistic appearance. This might be a design choice as it does have a pleasing look.
Story/Instructions 2/5 Far more effort is required in this category. The author needs to invest as much time in this department as he does in other aspects of map building.
In-Short a decent effort but the design flaws listed above keep this from being a recommended download.
