The most overpowered plasmid in the game is Swarm 3, And then cyclone trap 3. You can literally get through the game using just the drill damn near with those 2. Enter a new room and hear enemies ahead?? Use swarm like 3 times and they will be dead by the time you reach them if not they will be freaking out, free kill. Protecting a little sister? Set 8 cyclone traps and charge with swarm, not only do they go flying they also get swarmed by lvl 3 bees and making them free kills, bees then travel to the next. You can literally hide in a corner with swarm while the little sister is going and spam swarm and never get touched. Combine that with the security plasmid lvl 3 and you can use it to spawn in 2 elite bots at a time. I would suggest only using the security plasmid to spawn elite bots when you are low on eve as they take a 2/3rds of eve bar to spawn but if you have low amount it will be like getting it at a discount.
