What is CELO?
CELO (Company of ELO) is an application that allows you to view all players information when a Company of Heroes 2 match is about to start and manage most of the aspects of the game like replays and matches.
Why would i want this?
To simply have a better knowledge of who you are up against in Auto-Matches and even in custom games, and if you go up in a 2v2/3v3 random you can check your allies ranking.
You can also upload your replays directly from CELO to COH2.ORG, change replay versions and you can have a Match-History Viewer
