I've enjoyed the new level design, with several possible paths, but I miss some features like having specific names for each upgrade (from a V8 engine to a V10, or 18in to 20in wheels, for example) and being able to see your vehicle change as you upgrade it. I'd like to see some bigger changes to the mechanics for the sequel, such as upgrades giving you debuffs (increased weight when you equip heavier armor, and increased fuel consumption when you equip bigger engines, for example), forcing you to pick a suitable mix of upgrades for your strategy/path you want to take.
The medium badge description (or its real requirements) should be changed. You actually need to complete *every* mission to earn it. Completing level 30 after failing a level on the way will not give you the badge
SPOILERS:
Hint: you have to manually power up the generator after putting the gas on it to electrify the fence, and the door only locks if you use the key on it *after* it is closed (using the key on the door when it's open closes it, but doesn't lock it). I was struggling with these two to get the Lone Wolf achievement
To the ones trying the arena badge, I'd recommend the Titan mode where you (and your enemy) have a larger health pool. I find that ideal if you're not going for fast high risk wins
I feel like I should earn points by hitting civilians in Dead On Time. Those guys can't get out of the way of a car blasting its naval-grade horn, I'm doing humanity a favor for all I know...
I didn't experience any lag until level 6-7 (about 2 hours of playtime, maybe?), and it's not specific to a level or number of enemies on screen. Restarting my laptop seemed to help, it's probably a memory leak (possibly introduced in the latest patches, since I've seen people saying that they didn't have this problem before)
If I could finish the game that would be great, yeah. These lags in the end (and when I expand the options bar or go to The Critter page) are killing me
