What players say

51% of 14,984 reviews are positive · 40% of 49 in the last 30 days

Players praise the returning base building, alternating-faction campaign, and large battles with giant units. Common complaints include shallow RTS systems, heavy emphasis on elite heroes and MOBA-like combat, a cartoonish art style, and limited factions and replay value. Many players recommend buying it only at a discount.
