Its dope me and the homie get on this, you get to choose your overshield which is probably why $ilent was getting fucked up easy he didn't upgrade his.
At first I could only quick switch to 2 weapons then as I leveled up I could do it with 3, you can hold more weapons but only 3 so far I can wield. As we did one mission to fix this shit so we can spawn vehicles, after it, we got to ride this road warrior type of car with a machine gun for the driver and a missile for the gunner, (unless you choose the machine gun, haven't picked this option yet) by both players pushing Y you can switch positions without having to get off the car. Got an achievement for smashing those shits that come out of those holes can't remember the name of em. I'm that Sniper foo with the hawk perk, ill unleash my bird and take your shit from a distance.
This other level there was this crazy fuck that just wouldn't die he had a good overshield and was running with some goons me and the homie had a hard time with this guy spent hella money on grenades and ammo, so we upgraded our overshields and that did the trick. Don't do the hard levels unless you leveled up something nice. So yea it has its Contra in FPS cam type of moments.
