ok basically if you have a great strategy for horde of GoW 2 then please post them down and make sure to be detailed, and to tell what map(s) its good for oh and be specific.
on the map Blood drive their are 4 places (or 2) to go: the small dead end hallways that spawn Pistols and the room right across that has a single window in a seperate section of the room. (they are all on the ends of the map. and they have duplicates at the opposite end of the map)
you can either: have 2 people go into one of the small dead end halls and 2-3 go into the room across (if three have one player go into the 2nd room in that area as a Sniper, and 2 guard the door) if 2 u can have 1 be the Sniper and 1 guard or both guard.
now when u get the shields u can only use pistols right? so the players in the pistol spawning hall should get shields and if they are low on ammo they got more right behind them. the people right across can use whatever they want. recommended mulchers, lancers, shotguns, etc but pistols not as much recommended. this is good because u got about 1-2 snipers (possibly) that weaken the enemy, andthe guys with the shields and flamethrowers and boomers are many times easier to kill because they will be exposed to a lot of fire from 1 side. now all of the locust will be exposed to one side and they will also be split in two groups, one after the dead end pistol hall and the sniper window guards.
OR
have 1 person in each hall/room-right-across-the-hall-that-spawns-pistols if u have four, if u have 6 people than have 2 be snipers. then follow whatelse i said. people in hall use shields and pistol combo while the people across from them have other weapons.
this is a good strategy because the locust will be in two groups one going after one side of the map and another at the opposite end. sure u get less fire on groups of locust but u will also have to deal with smaller groups since they will be spread out more. also the locust will be taking fire from both ends which makes shield guys useless! like the first strategy. altho the weak point in this strategy is that u wont be able to kill them as fast and if u get knocked out u have a low chance of surviving, but is good nonetheless.
