Just found this game. Put part time play over 4 days into it (too much on a 'work from home' day when I played too much) and am now about done. Max character level and 999 legendary items. (just not all 'heavy' legendary 999 weapons yet) So big raspberry to the haters saying this is pay to play. You really need to improve your gaming skills or not expect absolutely instant maximum gratification.
Likes:
Itemization is strong for a Flash game.
Item boosting.
Item crafting.
Items offered in store are correlated to your equipped gear so no trash.
Missions are randomized opponents based on level.
Skills, bonuses and items -- enough to make it feel like my choices matter.
Free skill respec to try the different skills.
Short levels for quick reward feedback loop.
Dislikes:
Cash scaling. Selling items. Actual cash earned is squat.
Challenges only grant top level prize.
Can't replay the challenge bosses.
No sequel?
