The latest take on the Warhammer 40K universe in RTS form will make its grand appearance pretty soon. Dawn Of War III brings back the huge armies seen in the first game, but with hero units like in Dawn Of War II and a load of other influences including some elements from MOBAs.
Also, the three playable factions: the Space Marines, Orks and Eldar, now have humongous Elite units that not only look cool and menacing, but should provide you plenty of options on how to take on the opposition.
RTS may not be as a big thing nowadays, but there still developers like Relic and Creative Assembly (that recently did Halo Wars 2) to keep the genre alive.
Dawn Of War III is, as expected, a PC only title. It will cost RM115 on release over at Steam.
