Left 4 Dead 2. Dead Air. Expert. Realism. Speedrun
Left 4 Dead 2.
Dead Air.
Expert difficulty. Realism mode.
Speedrun with bots.
There is no cheat. Just luck & skill.
If you think it isn't expert look closely at bots health. Infected damage on expert 20hp (10hp from back). Tank damage - 100hp.
The number of common infected (who can exist at the same time) is limited (thanks Valve). New zombies could be spawned by AI Director if you killed some of them before. If you don't kill them in the beginning you haven't problems with them in the end.
Thank you for watching & comments.
