-Combines tower-shooter, 3rd party RPG, troop deployment/management, and does all three rather well.
-Build and defend a castle while attacking the other, at the same time the enemy is doing the same. Customize your castle.
-Most quests can be won either by castle destruction or flag capturing.
-Support your troops by firing on the enemy troops instead of the castle, juggling priorities on the fly.
-Multiplayer; online, local, vs xbox, and in several different modes.
-9 upgradable troop types, spells, rooms, and shots each.
-Good music, good graphics.
-Funny-as-hell comments from troops in-game. also, the cutscenes are quite funny as well.
-Full-Story plot. The ending of the main plot is as epic as any viking tale and fits well with the DLC.
-Campaign is split; 1st half is knights, 2nd half is vikings, so you get to know and love both sides.
-Each DLC provides one additional campaign to add on to the end of the main campaign. Each campaign giving a upgraded version of either the knight-side or the viking-side.
-DLC campaigns have more focus on the hero and add more depth and closure to the main story line.
-Moderate replay value.
-Moderate voicing. Not bad, but it's not full-speech animation.
-DLC shot types are overpowered, particularly the Viking Elite. Makes for rather unbalanced play.
-Difficulty is a little low..... Easy = Let my 5-year old play, Normal = Easy, Hard = Normal.
-If you barrel through it, it's rather short.
All this said:
Good game for the price, even if you dont catch it on sale.
I can see this being a ROCKING multiplayer game in VS mode.... if you can find anyone who knows the game exists. I can see it doing very well on gaming-systems for this reason.
Great game and type-combination but it needs an online community.... badly.
