|Dinosaurus can host a single non-AI icebreaker. The memory cost of the hosted icebreaker does not count against your memory limit.|
Hosted icebreaker has +2 strength.
Limit 1 console per player.

|If there is an icebreaker already installed on Dinosaurus, the Runner can install a different icebreaker onto Dinosaurus, trashing the previously installed breaker.
If the Runner has no free MU but a Dinosaurus that is not currently hosting an icebreaker, he can install an icebreaker on Dinosaurus without trashing a program. Declaring where a program is hosted is part of the install action, and so the memory cost of the program does not need to be taken into account.
