We are aware of a few bugs that are making the highest difficulty levels of the game much harder than they are intended to be. These issues mostly revolving around Point allotment and harder difficulties are providing fewer points than intended. We are working on this situation, but in the mean time beware that difficulties higher than normal are probably over-tuned as a result!
With that in mind, as with any content that proves too challenging at first, there is no shame in lowering the difficulty setting to get a hang of the game and learn it's mechanics.
A few bugs aside, here are hopefully some tips to also bring victory to your Space Marines in their new campaign!
• Dreadnoughts and Land Raiders may seem to be the best units, and in many ways they are, but they are also extremely expensive. Be sure to bring ample Space Marine infantry to bolster your roster.
• Infantry, even Space Marines, require cover to operate effectively, even when on the offensive.
• Support units are very effective at keeping the new, extra savage, Ork AI at bay. Heavy Bolter and Meltagun Support infantry are great at holding defensive positions, while mobile units such as Razorbacks and Whirlwinds are excellent for providing supporting fire while your troops advance in offensive actions.
• A slower advance is a safer advance. Buying transports for all of your infantry can get prohibitally expensive very quickly
• Be economical! When spending Points, remember to keep a healthy reserve at the start of every scenario for issuing replacements and also for replacing units destroyed in action. Also, don't just buy only the most expensive units. Utilize your entire unit limit on every scenario.
• Most weapons can fire across multiple hexes, but most weapons also lose accuracy when firing from longer distances.
• If a weapon has a range indicator such as 2-3, it means the weapon only fire at those ranges and cannot fire at range 1.
• Pay attention to weapon graphics, they are strong indicator of exactly which weapons are actually firing.
• Infantry units armed with assault weapons ignore terrain cover when using those assault weapons.
• Combined arms tactics are very powerful, be sure to bring a few of each type of unit and not too many of the same.
• As a unit's morale falls, turning their strength plate from white to red, they suffer from combat penalties such as reduced accuracy and reduced initiative.
• Unit hit points only recover by one per rest action. A Titan with 10/15 hit points takes 5 full turns to refit back to full strength.
• Pick the right weapon for the right job! A high strength weapon might seem to be strong against infantry, but a weapon with a much higher rate of fire will get the job done much more efficiently.
• Pay attention to the cover ratings that different terrains give.
• Non-infantry units gained a reduced amount of cover bonus from terrain.
• Infantry are often required to take some Victory Hexes, many vehicles are often too large to enter these hexes.
• Victory and objectives hexes can be identified by their golden outline.
• CORE units have a gold border plate, AUXILIARY units have a grey border plate, and mission critical special units have a unique border plate.
• Unit's with the leadership trait are very important for keeping up the morale of nearby units without the need for constant rest actions.
• Always bring dedicated scouting units to screen your main advance, preventing enemy counterattacks from reaching your expensive combat and artillery units is very important.
