Completion Strategy:

Yet another virus level. Thankfully, it's the last one.
Do the same 'Run and Kill' strat as mentioned before, but you probably won't last for long, because there is a lot more enemies in this level.
Your probably best off just reading my platinum strategy.

Platinum/Fast Time Strategy:

A boring level to go for platinum on.
Simply because everytime your on a good run, something seems to go wrong :(.
Oh well. There is a large ledge upstairs somewhere.
You should know where it is, it has a double shotgun in the middle of it.
Well, try to get there as quick as you can.
Stay close to the side, and when a virus gets near you, jump down.
Go left and go through all the hallways (you'll have to experiment to find which is the best way) until you can get back to where you started.
Like in Monkey Immolation, make sure the virus(es) stay close to you so they don't venture off on their own.
Keep doing this for the 3 minutes.
You may need to practice this a bit to get it right.
