I was going to post this . I used the free version and bought the upgrade yesterday . One of the few truly innovative widget applications still on Android . Warning it ' s takes a bit of getting used to , their feature set is over the top . <| sep |> That ' s just it . the meme war didn ' t end . This is the pearl harbour of the meme war . <| sep |> The wrench sword upgrade is top tier , 1 hits clockworks . The crossbow for corvo is pretty useless non lethal , but the gun is really fun , sniper and shotgun are good lethal , and sniper is useful for non lethal one range shots to break things . Howling bolts has 2 good upgrades . Grenade upgrades are less noise non lethal , use to break doors and stuff or larger radius lethal , obviously . There is also an armor upgrade that gives take less damage or less visible in lightThere is probably a few I ' m missing , but they are all great to have , but are play style dependent .
