If you haven't heard of the game, here's some information for you;
I suppose 'steampunk' is an incorrect term, but the concept is the same. I guess 'ragnitepunk', maybe? Vehicles, some weapons, and even medical tech are powered by ragnite. It's the reason for the Imperial invasion of Gallia as well; the country has rich ragnite deposits. http://valkyria.wikia.com/wiki/Ragnite
The game is well known for it's unique visual style. It has kind of a sketchbook quality to it, lending it a very interesting visual flair. There are a couple of sequels to Valkyria Chronicles, but they're still on the PSP and Vita, as far as I know, so they haven't been as widely played as the first one, which is a PS3 title. The first game is also on Steam now, and costs $20 USD.
The game is a turn-based strategy RPG. You're given a specific number of action points to use each round and can select any character at any time, as many times as you like, though each time you select a character their movement points go down until they can barely advance at all. Some characters also have limited ammo, preventing spamming certain attacks. Once you pick a character, it goes into real time as you move around the map, and enemies react to your movement so it's important to approach from cover unless you're using a high armor class like a Shock Trooper or Lancer. When you fire, the game pauses to let you aim and the results play out. On humans, head shots do critical damage, while vehicles have weak points at the engines (usually in the rear).
Characters can be one of five classes;
Scout: Armed with rifles (with under slung one-shot grenade launchers when promoted), Scouts have the highest mobility of all classes, but are lightly armored.
Sniper: Can kill from extreme range, but have very low movement, low health, and limited ammo. They are excellent at killing exposed enemies, but do poorly against enemy troops in cover.
Engineer: Similar to a Scout, but with lower movement. Engineers can repair the squad's tank, disarm mines, and repair barricades. They have access to the basic rifle. They also carry large medkits, as opposed to the small medkits that all other units carry.
Lancer: Anti-Tank units that carry heavy armor, blast shields, and lances that fire their tips equipped with explosive ragnite warheads. If they flank a tank and hit the engine, they can take it out in a single shot. When promoted, their lances become mortars.
Shock Trooper: Armed with an SMG and more heavily armored, these troops provide good frontline offense. They have decent mobility and health and excel at targeting troops in cover; especially once they get promoted and carry an assault weapon with an under-slung ragnite flamethrower.
Lastly, there's Welkin and Isara. Welkin is the CO, the strategist, and rides around in the Edelwiess, the squad's tank. The Edelweiss is maintained and piloted by his sister Isara. The Edelweiss takes twice as many action points to use, but it is equipped with a mortar, anti-armor shells, and machine gun. It is immune to everything except anti-tank mines, other tank fire, lancer fire, and takes minimal damage from grenades. It's weakness is the engine on the rear. If the Edelweiss is destroyed, the game is over. http://valkyria.wikia.com/wiki/Valkyria_Wiki
I think we'll probably just stick with freeform for our version of the game and skip out on the dice rolling. In ours, Sauer will be the CO, taking up Welkin's role from the game, so that means we still need a tank pilot and at least one player for each class. Multiples are allowed, of course, but I'd like at least one of each so we have a balanced squad. If the game still interests you, let me know! I'm happy to answer any questions you have.
