Find a power node in a level, scroll to a Sentry Gun in your inventory and go near the node and hold down 
to plant it. Power nodes are usually in rooms where a lot aliens will be coming at you in waves. You shouldn’t have trouble getting yourself this trophy, especially since the Gun is very powerful. Kill 20 with a Sentry Gun and the trophy will pop.
A very early and easy place to do this is during the first Level – Subversion. You’ll be introduced to your first power node, in which the in-game tutorial will tell you to plant the Sentry Gun you found earlier in place. This room has around 30 enemies or so, so simply plant one, sit back, and let the Gun do all the work till the trophy unlocks. Note that if you don't plant the Gun, the enemies won't spawn.
Another place you can easily unlock this will be during Level 2 - Re-Entry, during the 2 minute battle where you'll be facing waves and waves of aliens.

To install the turret, find the power supply and press 
next to him. Power nodes are usually located right next to a large concentration of enemies. A very good place to get to Level 1 is Subversion as soon as you encounter the first power node. There are about 30 enemies in this area, so just place a turret and watch it kill enemies. Attention, enemies will not appear in this place until you place a turret. Another place is Level 2 - Re-Entry, where you will have to fight waves of aliens for 2 minutes.
