I was just looking at toy plastic grenades and thinking... how underhand would that be? I mean, using a spent BFG in extremis is one thing, but deliberately carrying and lobbing dummies round every corner might be a :angry: tactic.
One thing I am casually keeping an eye out for is some form of throwable flashy light. The CQB site at which I play has a no pyro in the staircases rule, which makes taking them a real chore. Bouncing a strobe light round the corners might liven things up a bit, but I haven't found anything that's both usable and affordable.
