Well, in the Steam Store description of the game:
Fractured Space is an award winning free-to-play space MOBA where you control a gigantic capital ship to seize mines and bases for resources and buffs. Play solo, co-op PvE or 5-v-5 PvP. The intensity of a shooter combines with tactical decision making as you battle to capture the enemy's base.
You can clearly see the words "Play solo" there...
You can play solo in WoW, but that doesn't make it a single player game.
