how about a option for TIME STOP these timed misions are making me insane actually had no problem until i get to the "conduit" have 40 sec takes about 2 times of that with the damned mako....
You can easily rush the 4 colossi that are standing in the way. You just have to have unlimited health for your Mako. Just pass them through as if they didn't exist. They'll shoot you up a few times, but it won't effect you.
A time stop would be redundant.
