Interception PeTI is inspired by sp_interception and sp_gravity that I designed with Hammer in August of 2011.
Instead of porting the original maps, I decided to start from scratch with the new editor and modify the puzzle.
I must have played this puzzle more than a dozen times, and I never experienced any technical challenges. The solution does not require lightening fast reflexes or dexterity.
Each step of the puzzle does become progressively more difficult, and the last step takes a great deal of thinking and planning. But I can assure you that it is not impossible.
