Episode 3.8 was submitted yesterday. It contains the following:
HD-certified graphics:
-The completely redone artwork brings you as close to the HD experience as you can get on iPhone and iPod touch!
Restore your kills based on OpenFeint achievements:
-If you reinstall the game or install it on another device, log on to OpenFeint and the game will automatically restore your kills based on your achievements. Note that the game cannot know the exact number of kills you had, just the kills it can award from your achievements.
Other improvements:
-Weapon recoil effects for all characters.
-Made it possible switch performance-intensive “3rd generation effects” (bullet shells and fence) on and off.
