A user by the name of RazorUK took a look in the Titanfall game files and found some interesting stuff. The full details are located here, but I’ll list a few things below. Peep the link for weapon lists, perk lists, and map pictures.
Please note that this information could be wrong.
Our beta overview/impressions
How do you feel about the lack of single player? Will 14-16 maps at launch be enough to look it over? Personally, [minus Halo] I stopped playing FPS campaigns YEARS ago.
AT – Attrition?
TDM – Team Deathmatch?
CTF – Capture the Flag?
LTS – Last Titan Standing?
HP- Hardpoint Capture?
VM – Variety Mode (a mix of all the other modes listed, sans campaign)
training ground* [not sure if this will be an actual map]
