Great so far!!
Some small changes:
1. A way to return to base. Sometimes you are abandoned for from the mission alone and either have to walk back or quit.
2. Online social hub. Could act as menu, idk.
3. Being able to mark a point visible to other players. (Maybe the commander only has this ability idk)
4. More gun mods. There really isn’t a whole lot here.
5. A way to ask for help or request pick up could be cool.
6. Being able to do a crouch run of sorts. Also being able to crawl.
Bigger changes:
1. Formal pvp mode where you can earn money and exp.
2. Different kinds of missions (retrieving info, capture a specific point, etc.)
3. More detailed maps, more dense and compact
