How to unlock the Snowrunner achievement in I, Zombie - Definitive Guide
The only real tip I can give you is that you don't need 3 stars for each of these levels. You can shave off time by sprinting past things, even if it gets a few zombies killed. As long as you pass the level, the time at the end will count.
i couldn't see either levels 28 or 30 in that video so i just had to get the best i could, maybe his time didn't include those 2 levels as they are quite hard to do and maybe he passed on them and didn't need to get better times.
You will not get a total time until You have played thru ALL of the 10 Winter levels ... You will then have a 'total' time.
From that point You can pick any level and play it over and over ( until You get a time You are happy with ) and every time You beat your 'Personal Best' Your 'Total time' will change accordingly.
I played thru the game ensuring I got ALL 3 stars on each level then played individual levels shaving off time until the 'chievo popped !
Play through all the winter levels to begin with and try to do them as quickly as possible. When you complete all of the levels, check out your total time and see how much you have to eliminate. Go back and play through the missions clearing them with faster times.
Look for missions that you took more time than others as potential candidates to be done again with better time. Just keep practicing them until you get better. Again, when redoing the missions, just focus on speed and not on saving zombies.
Once you shave off enough time to get your total under 8 minutes, the trophy will pop.
There are a total of 10 winter levels. For this achievement you can just run through the levels as fast as possible without worrying about casualties. You don’t have to get three stars for the speed run.
