Picked up Valkyria Chronicles Remastered. Finally going to play this game that everyone loves. So many times I almost got it on PS3 but never got to it.
It's very good, I've been playing it myself. Few tips.
Engineers: always have an engineer follow your tank. They can basically make your tank invincible. The engineer can disarm mines. Anybody the engineer walks by gets their ammo refilled, remember that for anti tank soldiers or when you need to use your sniper on a map (rare but still).
Scout: Most useful soldier in the game but their usefulness online has been greatly exaggerated for one simple reason: 60 fps. They take way more damage from interception fire at 60 fps and can be mowed down pretty quickly by shocktroopers if you charge in. Still these guys are probably the best in the game.
Shocktroopers: now these guys unless there's a tank or sniper close by actually can charge in head first. They're extremely useful for defending a base or tank or clearing out trenches. Early on the scouts will absolutely dwarf these guys in usefulness, later on you will actually need them pretty badly.
Lancer: pretty self explanatory. Use them to kill tanks.
Sniper: only a handful of levels they're useful. My advice is never star a level with just bring them in later if you need them.
Tank: these are most useful as moving cover, but their mortars are incredibly useful for hitting behind cover.
Few general tips: those metal pylons your tank cant drive over need to be cleared with grenades. Somehow never figured that out until halfway through. Also anybody your are standing directly beside will shoot with you on your turn. This is extremely helpful on one specific mission when you need to actually take down a a tank with nothing but rifles. There's basically no limit to how many people can shoot at once as long as they're all standing beside each other.
