Fine tuning would be nice

This game is pretty solid in the fun category, it can even help with that itch we all get when you've been longing for a new crusade... HERESY GROWS FROM IDLENESS! Purge the xenos scum, SUFFER NOT the alien to live!
WE MUST PUSH BACK THE CHAOS FOCRES! Back to the hell from whence they came! And the system of micro transactions in this game allow just that, brother! The best wargear can be obtained from your chapter's armories with out having to submit for resources through ones chapter master, although solid tactics will make this more easily attainable.

Definitely needs some polishing. Base construction is "crowded" and it is entirely too easy to move a structure out of place on accident. Then more frustrating when trying to replace, with a finger blocking the placements grid. But still an entertaining app. 7.5/10, although a lot of that comes from the feeling of joy from crushing chaos forces. 😄🤓

13 months and still great!!!

So this is only builder game where, you control your armys actin in real-time, and the warhammer setting is fantastic, great amount of long term active players.
And this is truly (sadly maybe only one left in gaming companys)
Its not a pay to play or pay to win! They have enough optional vids to watch for bonuses that must keep it going.
The rare times $ offers r made r not much 10$30$ you get a splash screen ONCE only, then its in your mailbox thats it no annoying constant pushing. And the (Gems/diamonds) in this game are call Machine Spirit, and they dont really give a huge or really any advantage over not getting, just a time saver. And they give plenty of free MS with logging in, and small missions you can accomplish for game of this genre!
A must for warhammer 40/30k fans

What I love most about this is the micro transactions. It's COMPLETELY optional. The coins you can get can be obtained by completing achievements and watch an ad every now and then. The coins are really just good for speeding up timers and stuff, but other than that I haven't really used them. I don't really like the voice acting but that doesn't mean much. You can attack other people's bases or do a skirmish match where you capture a bunch of points on the map. The only way to level up is by building and upgrading stuff, but if you have time and patience it doesn't matter. If you don't have the time and/or patience, there's the micro transactions that can easily be earned. So I give it 5/5. I'd give it a 6th one because I love 40k
