This mod does a couple of things. * It makes the cost of fully upgraded sentries, cost as much as fully upgraded jokes * It gives sentries and the Left Tier 3 skill (Engineering) the same bonuses as *Partners In Crime*, which is the +10% movement speed and +30% health and It makes the tier 4 skill, give health regen, like *Hostage Taker*. * But they **DO NOT** stack with each other. So, no stacking with *Partners In Crime* and *Hostage Taker* * Gives (via skill investment) the ability to pickup broken sentries, and makes the sentries mark specials * It notifies via message if a sentry died, or is out of Ammo And it changes the skill tree like this: T1 - Third Law Basic (changed): Your sentry guns gain a protective shield. The cost of deploying a sentry gun is reduced by **10%** Aced (new): You can now pick up broken sentries, broken sentries will lose **50%** of their current ammo T2 Left - Sentry Targeting Package *Renamed* to Tower Defence Plus Basic (improved): Your sentry guns gain a **100%** increase in accuracy.

Aced (improved): You can now toggle AP rounds on your sentry guns, lowering the rate of fire by **75%**, but increasing the damage by **250%** and allowing it to pierce through enemies and shields.
