With the battles themselves you have the story driven campaign if you’re playing solo, which follows on around a year after the original campaigns, with you playing initially as a Chaos champion, Thorgar the Blooded One, who has been tasked by the Gods to build up an army. So initially you’re on your own, but quickly start to gather an army around you as you move through the first battlefield. Killing enemy units along the way, collecting gold and potions as you go. But I’m not going to cover this in detail, as that would spoil the plot. Suffice to say there are several chapters to play through, each with multiple missions, so there’s enough here to keep you busy for quite a few hours - even days.
There are also skirmish games pitting you against the AI, and of course multiplayer. With these you have all the same options as the first game, but there are new maps to play and the two new factions. One important difference here compared to RTS games is that as this is a Real Time Tactics game, there is no base building, you have to create your army before you start the game, so you get to pick which units you want and what upgrades to purchase. You can even go to the detail of customising the colours used in clothing and banners. This basically means you can completely customise your army to your aesthetic tastes, not just to match your fighting style. Luckily you can save these armies for use later, thus enabling you to create different armies for different tactics and then simply load the one you want before going into battle.
Your champions have various abilities, which differ from one to the next, some of these abilities are passive, and simply work all the time, such as the chance of a critical hit on an enemy, others are active powers, such as slowing down an enemy unit, healing one of your own, or more direct attacks such as fireballs or an axe that is thrown knocking everything in it’s path flying.
Once in a battle, you have the usual fog-of-war restricting your view, which flying units can be a big help with. The campaign missions have your typical types of objectives, get to here, do this, kill this person, defend this position etc. etc. On the battlefield you can collect various items or gold, the gold can be used to purchase new units, upgrades or potions etc. Some of the items, such as shields, weapons, armour and so on can be used by your champions, making them more powerful, more resilient and so on, like a role playing game. These items can also be transferred between your champions, so shared around, or sold it you don’t need a particular one.
There are also duals that can occur between your champion and an enemy champion, either in the middle of a major battle or as a specific mission in the campaign. Although personally I just found these to be a distraction of the real battle.
Battle march doesn’t really do anything new, but it’s only an expansion after all, not a new game. The single player campaign should keep people busy for while, and the new factions will add some new variety to the skirmish and multiplayer games. Overall not bad, especially when you still get change from £20.
