I've played through DC a few times as Imperial Guard, previously on Normal mode.
As my own personal preference, I've never been a fan of the blitzkrieg strategy of immediately rushing the enemy's base within the first 10 minutes (let alone at the immediate start of the battle, as seems prevalent in the Single Player Campaign Mode with the so-called "Honor Guard Rush"). I'm a big fan of long drawn out battles and taking every inch of the enemy's territory, crushing them utterly. These big battles were what drew me to the original Dawn of War in the first place.
I'd previously misunderstood the differences between Normal and Hard modes in Dark Crusade. I really wish for simplicity sake, Normal mode had your army @ 100% health, as well as the enemy's army @ 100% health. Hard mode could increase the enemy's health, while easy mode could either decrease the enemy's health, or increase your own (or both).
Though I suppose Normal mode doubles your army's health as a way to help you have epic battles and still have a chance at winning them (as in the case of fighting 2 enemy armies on the same map).
Anyway, I stayed away from Hard mode before simply because what I really wanted was a level, fair fight (100% vs 100%). I'd previously read somewhere that Hard mode in DC was your army at 100% and the enemy at 120%. Apparently I was wrong about this, however, and those are the stats for the SoulStorm Hard difficulty.
So now I'm going to embark on a Single Player Campaign as the Imperial Guard, and attempt to restore order to Kronus under the flag of the Liberators. I'm going to attempt this without rushing the enemy base during the first 10 minutes of any battle (haha, if that's even possible - we'll see). Basically, I'm going to attempt to Take And Hold the majority of points as I march across the battlefield towards the enemy base. This will have the added bonus of increasing my defensive capabilities against subsequent attacks by the enemy.
I'm probably not the best IG player by far, and I'm writing this for the Single Player Campaign mainly because I came to this series of games pretty late in their life, and never really played multiplayer skirmishes against Human opponents (except the original game against a friend + CPU enemies). I also do enjoy all the games single player campaigns, so it's a worthwhile side pursuit.
I'm honestly not a fan of the Imperial Guard's weak Guardsmen infantry. I'm more drawn to their varied other capabilities - extreme long range crushing power from the Basilisks, the absolute might of the BaneBlade ("We Are Steel And Doom" my ass, Space Marines), the awesome range of the Kasrkin's Hellguns, and the combined damage-soaking capabilities of the Ogryn + Command Squad with attached Priests. These combine for, at the very least, a nearly indestructible defense, the Emperor willing.
As my army advances across the battlefield, it's important to combine these powerful elements with solid strategic planning. Prudent analysis of terrain will be vital to establishing our lasting defensive positions, along with the liberal use of choke points as we dare the enemy to face us head on.
Which brings me to the very key element of my strategy - it's focused around a slowly bounding line of HWT's, each equipped with a hammering AutoCannon. When massed, these weapons lay waste to everything in their sights, be it infantry, tanks, or the very Daemon spawn that taints much of the land.
While this may seem to be a rather weak strategy at first, I find it essential to entrenching my ground for the long haul. While it's less swift and less mobile, conducted properly, it can secure key locations better than just about any strategy I know of.
Enough talk, now. I'll detail all of my thoughts about the campaign to be conducted as responses to this thread. General Lukas Alexander, out.
