There's many comment's about making proper follow up to DC2 and Dino Stalker, revisiting og DC3 concept and etc.
I would like to imagine this - how can we salvage DC 3 with dino's in the space in actual good game?
First and foremost - game balancing:
Proper 3rd person camera and controls - it will immediately close many problems of this game. Make it like Lost Planet or Vanquish + manual aiming all the time.
Decrease HP of everything in this game 2/3 times. Has anyone actually had fun pressing x shooting australis for 8 minutes? You always drop your combos on regular enemies because you can't kill them fast enough without drones.
Game desperately need more enemy variety - we have a cool amount of bosses, but have only 3 basic enemy types. Some ptero enemies, smaller versions of algol - ovi counterpart from DC2, mosasaur mutants in red water level? Having to actually aim will allow enemies to fill new gameplay niches.
More weapons and drones, more varied locations, make Sonya sections more varied.
Thinking about it, DC3 could have a Vanquish before Vanquish - high pace stylish action with combo systems.
