Achievement - Speed Runner
Description - Escape with 1 minute and 30 seconds or more remaining on the clock.
Fairly easy achievement once you finish destroying all the hives you are tasked with arming a nuke and making your way all the way back to the start.
Easiest setup -
Tank - all
Explosive rounds - All players
Armor - 3 Players / Feral instinct - 1 player
Shield/Death machine - Any
Sentry gun - All Players
Pistol - Which ever you like the most
What you want to do is upgrade sentry, pistol, armor/feral instinct fully and use the rest of the points or if any left over on tank for extra health. Sentrys will make holding off enemy easier with all four players using them. Fully upgraded pistol will allow you to move faster while running, and finally feral instinct will allow you to move faster as well as obtain a small health regen boost.
There are a total of two barricades that take a total of 20 seconds a piece to disappear. You will be tasked with holding out against at least two rhinos and plenty of everything else at each one. At each barricade each player should drop sentrys , armor, as well as feral instinct this will make it a lot easier to survive and move on to the next one. You have a around 4 minutes to get to the escape helicopter if done correctly you can make it at around 2 minutes.
