Yesterday was our first session Eclipse Phase, the first Part of the Mind the WMD scenario. As it happens, we needed to make a teamwork test and i concluded that the rules for Teamwork are a bit... lax. I mean, it doesn't mean how competent somebody is, he always adds a fix +10 to the test, which seems unsatisfing.
So we came up with the following houserule:
The helpers roll their own skillrating with the appropriate modifiers and the sum of all MoS or MoF is added as a modifier to the test of the main character. Criticals always result in a +/- 30.
