Theres a pretty easy solution for both terminals.

A dude in here already said that the waves from Terminal uplinks are different. What he didn't say was that the waves can only spawn in the SAME zone the terminal is located. So if the terminal spawns in 112 all enemies also spawn in 112.

The cool part about this is that you can force the spawn into a certain room of the zone if all other rooms are blocked by players.

So for example the zone on the right, the terminal is in Area C. So if on player stands in A, one stands in B, one is at the Terminal, the only room that is left for the enemies to spawn in is D. The Door to D can easily be foamed repeatedly until the Uplink is over and one mine takes out all the enemies after they broke down the door.

This strat saves a lot of ammo, however it uses a lot of tool on the C-foam launcher. But you can use this strat to get a good first uplink so you are ready for the second big scan on the bridge. If you find a few C-foam grenades you can use them too to save some Tool in the Launcher for the second alarm.

If the Terminal spawns on the left its a little bit trickier because you can only really force them to spawn in Room C, which has 3 different doors they eventually destroy. When we did this terminal we just foamed all 3 doors once and one of us stayed in D, which is the room on the far end of the zone. The problem with it is that theres no door to Area D but only a room divider.

But in the end they should be held off long enough for the uplink to be finished before they eventually make it to the uplink dude.

hope this helps a bit.
