BioShock 2 (Remastered) DLC, The Protector Trials
(BioShock: The Collection, 2016)
Scoring a perfect A+ rating (555 ADAM) on The Adonis Baths 1 trial.
Tips:
+ Throw bees around to catch Splicers further away (sometimes out of sight), as well as keeping them staggered.
+ If any Splicers make the mistake of jumping into the deep end of the pool, Electrobolt the water for an instant kill.
+ Use the shotgun for Spider Splicers when they get close - though Anti-Personnel Rounds work just as well with the Machine Gun.
+ I prefer the Machine Gun over the Rivet Gun - but I exhaust the RG of ammo (and don't purchase more) before breaking out the MG to conserve ammo early on.
