Captain Clive: Danger from Dione

Captain Clive: DFD is a top-down isometric view OR first person arcade shooter. This game is about progressing through difficult waves of enemies as you balance the purchasing of new guns and armor. Fast-paced action-packed shooting and maneuvering keeps the player always ready for their next gear upgrade. That's just a little about the game, let's not forget the massive bloodshed, Robert the robot ai companion, dual wielding of ANY weapon in the game, tons of guns, tons of armor, consumables, traps, bombs, turrets, and a ton of aliens!

If you like fast-paced but think it's just not fast enough for you, there's even an amped mode that throws way more enemies at you at a time.## So, I didn't read the top part, how about it in list form?
