Program: Icebreaker - Killer • Install: 3 • Memory: 1 • Strength: 1 • Influence: 2

1: Break sentry subroutine.

2: +3 strength.

Alias cannot be used on ice protecting a remote server.

Appearances are easy to change in cyberspace, but a high-quality render is not easy to mimic.

When comparing this to Ninja (similar cost, in-faction Killer) it looks quite good.

With all that said, Alias is usable on central servers only. That means it pairs nicely with Datasucker. And with that, Mimic is all the Killer you want...

At the same install cost, Mimic handles Sentries up to 3 strong, 4 with Datasucker (so the most interesting range) without additional costs and breaks through remote servers. With added support of Faerie it manages on it's own in most important cases.

That means Alias is usable only when you are too tight on influence and/or memory to handle Mimic/DS combo (eg. Iain) and aim to pressure centrals. That makes it very focused specialist, with only but a few decks to fit in. And even then, it is a fair warning message: "If you need this, rethink your deck."
