First impressions are important, especially when you're faced with a menu with tons of options that feels quite confusing. The developer of Geneshift was fully aware of that, so they've updated the game with a far nicer menu that's easier to navigate and far more inviting. Take a look:
On top of that, the Kill Combo system has been completely reworked (again). Now, more kills (like a double kill) will result in giving you more cash directly, instead of giving you a multiplier. On top of that, there's special kills which will result in giving you a chunk of extra cash as well like a road kill, a stealth kill and so on.
Unlocking skills now doesn't require a certain level in the campaign, giving you much more freedom in how you play it. An interesting change that should make replaying levels yourself or with friends become more interesting.
