Many puzzles revolve around using both The Doctor and River in unison. The Eternity Clock is designed to be played as a co-operative experience. Play icon The triangle icon that indicates to play River is still more capable than The Doctor though, given that she can at least move when charging her pistol while The Doctor is completely defenseless with his trusty screwdriver. However, while it can fire basic ineffective pop shots, to stun enemies requires a charged shot which takes several seconds to both ready and recharge. River has fewer qualms about violence, carrying a pistol with her wherever she goes. He is also equipped with his signature Sonic Screwdriver, which can unlock doors and disable certain enemies through a simple mini-game.ĭisabling enemies can become quite cumbersome though, as it seems fairly random which enemies the screwdriver will work on and the mini-game itself leaves him vulnerable and unable to move. The stealth is all very basic, holding a button to crouch while enemies stick to rigid patrols. The Doctor has always been a proponent of non-violence, and as such he must use stealth to sneak past the guards in each respective time period. Not just the same type of puzzle, but the exact same one with the same solution each time. Often only a single puzzle type will be encountered in each level, causing a situation where players must solve the exact same puzzle six or more times in a row to pass through Silurian-infested sewers. Though computer consoles offer a variety of puzzle types, that variety is poorly implemented. While leaping across platforms and shimmying along pipes and ladders, The Doctor and River push blocks and interact with consoles to solve simple puzzles.

The game itself is played as a side-scrolling platformer.
