Path finding for units is horrible. When you find your target and click on another unit to control you are centered on that unit. So, you have to find your target again to tell your forces to attack. Issuing a command to a single unit of a group removes them from that group and besides that groups just don't work sometimes. No, each unit has to be told separately to enter the transport.
Strategy is tough to carry out too.
Once you have engaged the enemy, telling them apart from friendly units is a job in itself. Scrolling through the battlefield is agonizingly slow, and units pause while you are completing this ominous task of scouting. There are two main forces in the game, the humans and an alien race called the Sheevat. Utility vehicles like engineers and constructors build structures. Balancing your mining and power is important as well as making sure you have enough defenses to guard your base.
