Thankfully, we can be sure this beta code is far from release day code, but already it's pretty good.
They need to work on the firing from the hip mechanics, and little gameplay tweaks as described above like the respawn timer on the plunder, thus allowing the teams to reposition themselves after a capture.
Also, if someone drops out before a game starts, the game still starts even though the teams are uneven.
Co-op is all sorts of awesome though, it just feels right and has cutscenes, platforming, and everything. I want to play it on harder and harder difficulties.
