joab777 Posted February 15, 2010 Share Posted February 15, 2010 I haven't had any problems thus far. Brutes, ledheads, thuggish, security and almost spider are done in siren alley. Then I thought, how am I going to get a little under three bars of research for the big sister? I got the first full bar on the 1st and an A on the second. Do I still have a chance to get it w/ only 5 left. I found out to get an A+, you have to get the final kill, so I will do this. Any ideas? joab777 Link to comment Share on other sites More sharing options...
Zooyork26 Posted February 15, 2010 Share Posted February 15, 2010 as long as you kill them on film you get almost a full block level... i got mine on fontaine furturisitics and still had the 2 left near the end... they level good so no worries if you kill them on film Link to comment Share on other sites More sharing options...

Lystra Posted February 15, 2010 Share Posted February 15, 2010 Crap, I forgot security all together. I hadn't fully researched Big daddies, either. Link to comment Share on other sites More sharing options...
Skittles Posted February 15, 2010 Share Posted February 15, 2010 Yes, you still have plenty of time. If you use this method, you'll get a research level per big sister(atleast I did). 1. Equip Ice Drill tonic(forgot the actual name) 2. Have level 3 Electro Bolt 3. Equip the Drill(obviously) 4. Begin filming the big sister 5. Start charging your Electro Bolt 6. Use the continous drill spin on her. 7. Your Electro Bolt should be letting out a continous stream now.(so she gets stunned and frozen) 8. She should die within 10 seconds. 9. ??? 10. A+ on film result Link to comment Share on other sites More sharing options...
Eddafred Posted February 15, 2010 Share Posted February 15, 2010 I finished research on them when I reached the final fight against two of them. Only other one I had a little trouble with was the Brute Splicers. Damn things never spawned often enough. But I managed to finish them off in Inner Persephone, along with the Rapture Historian trophy, and I wasn't really even trying to get that one.
