Not the best game ever, but it's so addictive
I mean, as you roam around playing as Crypto, you can:
1. Electrecute people.
2. Desintegrate them.
3. Zombiefy them.
4. Shrink them.
5. Anally probe them (hehe)
6. Levitate them and proceed to either smash them against a wall or throw them into the open sea.
You can also levitate cars, tanks and pretty much anything reasonable. (For Crypto)
In the saucer you can pretty much blast the crap out of anything. In Big Willy you blast the crap out of anything in a different way.
The humour isn't as good as it could be.
To put it in words you may understand, it's "Better Than the Sum of It's Parts"
But, people have different tastes, so rent it first.
