Damn straight, I look tired.
A run of the entire campaign of Zero Tolerance took me about 6 hours to beat.
And halfway through, I started to be a little more tolerant.
Thank god for modern devices having a sleep mode, so I didn't need to utilise the slightly awkward password system.
Once you get into the flow of it, it's quite a good game, but it does require a lot of acclimatising and is definitely not for most people. The modern remaster might be worth looking at if you are curious, or you can stick to the Genesis version if impressive struggling is something you find appealing.
As I said, I liked the game, but it can be a tough play, from overwhelming numbers of enemies, finding yourself low on ammo, and navigating some stonkers of mazes in the final act.
I am currently working in a full write-up for this one. It deserves that much.
