How to unlock the Fastball achievement in Crysis 2 - Definitive Guide
Much better than trying it on big dudes, who notice floating objects, and are tough to kill.
Reference the video for a guide.
A video of the aforementioned process, set to a rousing tune. For some reason I found the office chairs best for bug smashing. Often the bugs glitch and get stuck on the environment for an easy kill.
Here is a video guide I made many years ago for this achievement:
This again is a pretty straight forward achievement. To pick an object up, walk up to it and hold . Then get close to your target and press to throw it at them. Now a normal throw probably won't be powerful enough to kill a standard human with one hit, so your best bet it to power charge it up by holding down until all your energy is used. This makes the throw a lot more powerful and will have a greater chance at killing your target a lot faster.
If trying to kill the CELL/CEPH is proving difficult, your best bet is to wait a little later on when you come across the Swarm CEPH. These little creatures can't harm you and take one hit to kill with semi powerful throw of most objects.
