It's not bad, I like some of the mechs but it suffers from 2 problems. First being something that CoH can't do and that's Macro battles. Everything runs well when you're directing 3 infantry squads and a tank but when you have 5 mechs, 6 infantry squads and need to corral them into cover and the like, you arn't going to make it work. Still love Blitzkrieg mod though, that does Macro better by not focusing so much on individual units, meaning you can spam and take losses.
Second is the campaign is pretty bad, the game will regularly spawn units off map to rush your base or rush your army, slogging you down. I don't mean a single squad of infantry with a mech for support:
I mean spawning artillery mech, flame mech, AT infantry, Machine gun infantry and Grenadiers every-time you capture an oil derrick. And this was me playing on Easy because I knew the DLC with the Usonians would try to raw dog me.
The absolute worst was Telsa's factory, because before I hoped it got patched, it would produce very strong Tier 2 Mechs every 3 minutes but they didn't receive the order to assault my base. So after slogging my way through a factory that constantly produces troops to repel you, I get to this wall of chrome and my 5 mechs are going up against 18! of these that just sit there, I destroy maybe 3 but then have to rebuild my entire army from scratch. One trainer activation later and I got through but the campaigns are very raw. There's the odd fun mission like the ravine defense for the not-germans using artillery but that's one mission in like 8 that are pain.
So I wouldn't buy it, pirate it first to see if you'll like it because I'd want a refund if I bought this. Play Age of the Ring instead. ModDB 2020 winner, tons of updates and is actually fun. Buildings are kinda tanky though, rewards defensive gameplay.
Also that's a preview image for a DLC video, that's not my mouse. While taking the screenshot, some dev left their mouse over it then didn't take it out of the final product.
