Chilean developer Syrenaica's Evilot may look a lot like Plants Vs. Zombies, with the whole lane-based defense thing, but it's significantly more than that. It's an evolution.
Instead of just placing your defenses and watching them get beaten down, Evilot incorporates match-three puzzle mechanics. Set down three rats and boom — much bigger, strong rat. It's a simple twist on the PvZ formula, but it makes a heck of a lot of difference, and with Plants Vs. Zombies 2 not due out until July, it'll give fans of the genre a worthwhile means of waiting out the eagerly-anticipated sequel.
