Dam is super tough, but miraculously finished it on Normal, high density with only 1 teammate. Luckily we set a long time limit and could methodically hunt down the stragglers.
I didn't know there were splitscreen achievements for T-Hunt. Man, it was tough slogging through on co-cop. Glad to know density can be set on low!
Two-man T-Hunt on any map is rough. You can't always have a guy cover the rear for those inevitable flanks. Watch your radar like a hawk. When you engage and the enemy flees, you can bet he is circling around. Walking into certain areas of a map trigger enemy spawns or alert atention; replay the map enough times and you'll be able to predict a lot of their appearances.
Communicate, obviously. Tell your teammate when ur moving, if you need to reload, where you got killed, when you need to stop and scratch your nose... everything. Don't linger in any one spot for too long.
When enemies throw smoke grenades, it is an invitation for you to flick on the heat vision, get bold and charge in for some free kills.
When you break cover to fire on a SPAS-wielding enemy, make sure you kill him ;)
I love T-Hunt, but it can be frustrating, especially on Realistic. Enemies head shoot and toss grenades like mad. It's also a shame you don't get any consolation points for losing.
Also, best advice which has already been mentioned, find a base camp... any area with only one entry point, and lure enemies there. Most maps should have one or two spots
