| It's just so frustrating that I have to start over every time I fall.
This achievement is rather difficult and is considered quite hard. Due to its hard difficulty, the number of power cells is higher than most achievements. Infinite Mode level achievements are not affected by this and they still keep their 25-75 power cell rewards.
Electrophobia is an achievement in Run 3. It requires you to run 512m in Infinite Mode without collecting any power cells.
There are no suggested characters for this achievement. Choose whichever one you like (except for the Gentleman, who you should avoid using).
The only strategy you can use for this achievement is to avoid all power cells at all cost. Take the paths that give you a good distance between you and the power cells. In close tunnels, it may be harder to avoid power cells. But for the most part, it shouldn't be too bad to complete this achievement; just focus on avoiding power cells. If you have the bonus that makes power cells sometimes appear inside boxes, it would be wise to avoid boxes, too.
Slow characters work best. The Runner is very maneuverable and has a varying jump length. The Pastafarian spends most of the time on the ground, and can avoid power cells. The Student is the most controllable character. The Lizard is slowest and gives the most time for reaction. The Skater has a long jump but not high so it is low enough to avoid power cells.
