Pros:
-Obstacle Course -Number Passwords in some gates in various levels -Tank Battle in every level -Gas Level -Picture Frames that can be contains a SI or Equipment -Epic Crescendo Levels -all weapons in the finale for preparations -Bodies of L4D1 in the Ultimate Test Chamber (R.I.P XD) -Dialogues -Epic Ending -Traps are cool but look at cons :/
Cons:
-bots slipped and hang in the pipes the worst is the me and my bots are on the bottom floor and cannot be rescued anymore and wait til falls. -Not Counted- -it happens- -bots are likely to crushed by traps -annoying falling cars especially in finale -Trap doors seems to be annoying. when you open it the trap doors open except the first door contains zombies :P -once you get fall in the water trap door sometimes it gets stuck because of zombies -too many SI and NPC's ._.
Conclusion:
