8 Reasons Why Bioshock 2 Is The Definitive Game In The Series
4. Summon Eleanor
As Subject Delta the mission is to reunite with Eleanor Lamb because she's the Little Sister the Big Daddy originally bonded to. Without that connection Subject Delta will die.
Once Eleanor is tracked down, she turns herself into a Big Sister, and the two make their way to escape the city of Rapture for good. The game makes sure not to put her to waste. The player is given a new plasmid called Summon Eleanor. At a hefty price of EVE, the player can - you guessed it - summon Eleanor to aid in battle.
This changes the dynamic of every subsequent gunfight from here on in the game. Every fight feels faster, and this powerful ability means more enemies will be coming from all directions. It's exciting, powerful, and a fun way to include Eleanor in the gameplay.
