Ok... but alot of improvements
There are alot of ways to improve this game...
1. allow us to control the troops, at least a stay back and guard the base option... they just stupidly charge ahead into megaturrets? come on, no marine should be that stupid... but at least give us the option to send them back to guard the base.
2. More than 3 types of enemies would be nice
3. Multiple levels instead of one hard one.
4. Ability to uprgrade back up troops (give them better armor and weapons too, or buy new classes)
5. Ability to buy upgrades for speed (maybe leg armor will increase armor and speed or something?
6. Custom turret positioning
7. Maybe a story? that's always optional...
