I played this game back in the day on my mate's N64. I loved the atmosphere and the graphics were ahead of just about anything at the time.
I played and completed the remastered version on the PC. This version plays superbly on Windows 10, with enhanced graphics including lighting and water effects. Unfortunately it still suffers from the fog and poor draw distance.
The characters and set pieces all hold up really well. The levels are a bit samey, but the jungles, aztec-style ruins and space levels were incredibly original at the time and are still appealing today. I think the game designers were influenced by Tomb Raider. Turok features incredibly difficult and tedious platforming which would give Lara Croft a run for her money. On each level you need to collect a series of keys, if you miss a key you need to go back and these are hidden in places that aren't obvious. Enemies also warp in seemingly random intervals. In other words: the game is more difficult than it needs to be.
Music is tribal style. It's incredibly well-composed, but forgettable. The underwater music is my favourite.
Back in the day this was a must play game. Now Turok is worth playing for the amazing arsenal of weapons, enemies and atmosphere which are unique. Gameplay wise collecting keys and jumping 10 platforms to get to the area is not fun. There's around 8+ hours of playtime to complete the game. I would say play the sequel instead and skip this.
