STRATEGY & TIPS FOR SPACE DEFENSE: GUARD HEROES
Balance economy and offense; over-investing in one usually leaves you exposed on the other.
Think a move or two ahead and consider your opponent's likely response before committing.
Defend key positions rather than spreading your forces thin across the whole board or map.
Secure your resource generation before expanding your army or territory — a stronger economy compounds every turn after that.
